When Can My Child Go Back to Daycare? The Canadian Rules by Province (and Why There Is No National Number)

Last Reviewed: September 6, 2026

It is 6:40 in the morning on the third day. My middle one is standing on the couch singing, having just finished a full plate of hash browns and banana and asked for more milk. She has not thrown up since Tuesday night. I have one sick day left, a shift I cannot move, and a phone in my hand showing me two different answers. An American pediatric site says 24 hours. The daycare handbook on my fridge says 48.

I am a pharmacist. I spend my working life telling other people’s families what the evidence says. And I stood in my own kitchen that morning genuinely unsure which number applied to my own child.

Here is the thing I did not know then, and it would have saved me the whole argument with myself.

The Rule Nobody Told Me: In Alberta, the Centre Decides

I went looking for the Alberta rule. I assumed there was one. There is not.

Alberta’s Early Learning and Child Care Regulation says a child sent home for illness does not return until the licence holder is satisfied that the child no longer poses a health risk to people on the premises.

The symptoms that trigger it are vomiting, fever, diarrhea, or a new or unexplained rash or cough. But the list does not stop there. It also covers a child needing more care and attention than staff can give without compromising the other children, and any other illness or symptom a staff member believes may indicate a health risk.

That last clause is open-ended on purpose.

Read it again. There is no 24. There is no 48. Alberta law hands both the trigger and the decision to the operator’s judgment.

This explains something that used to make me irrationally angry: two centres in the same neighbourhood giving two different answers about the same illness. Neither one is ignoring public health. They are each exercising a discretion the regulation explicitly gives them.

It also explains why quoting Alberta Health Services at your daycare director does not land the way you expect. She is not required to follow it. She is required to be satisfied.

Clinical Mama Tip: This reframes the conversation entirely. You are not trying to prove your centre wrong about a rule. You are giving a decision-maker enough information to be satisfied. Specific times, specific symptoms, specific medication history. That is what actually moves this.

So where do the numbers come from?

From public health guidance, which centres use to build their policies. Those numbers are real and well founded, and most Alberta centres apply them. They are simply guidance rather than law here, which is worth knowing before you go looking for a rule to cite. And as you will see further down, they are not the same numbers everywhere in Canada.

The Numbers, by Symptom

Fever

Your child can return once she has been fever free for 24 hours without acetaminophen or ibuprofen. Niagara Region Public Health states this plainly: a child can return once they are fever free, without the use of fever-reducing medicine, for 24 hours.

The medication piece is the part parents miss. If you gave Tylenol at 9 p.m. and she woke up cool at 7 a.m., the clock has not started. It starts when the last dose wears off and the fever does not come back.

Which is why the last dose is the one worth writing down. Note the time you gave it, not just the day, and count forward from when it wore off. That single habit settles most of these arguments before they start, and it matters more than the number on the thermometer, since a fever is a sign your child is fighting something, not a problem to be erased.

Vomiting and Diarrhea

In Alberta and Ontario, 48 hours after the last episode. Not 24, which is what most search results will tell you.

Alberta Health Services tells families to stay home until 48 hours after the last episode of vomiting or diarrhea. In Ontario, Niagara Region says a child can attend 48 hours after symptoms have been improving, and during a gastrointestinal outbreak, 48 hours after symptoms have fully resolved. Wellington-Dufferin-Guelph, Huron Perth, Waterloo, Peel, and Ottawa Public Health all publish the same period.

If you are in Quebec, Nova Scotia, British Columbia, or New Brunswick, your number is different, or there is no number at all. Skip to the province section.

The 48 hours is not arbitrary, and the reason is not what most parents assume. Norovirus causes much of the stomach illness that moves through daycares, and the Public Health Agency of Canada notes that while it is most communicable during the acute stage, people keep shedding the virus for two to three weeks after symptoms resolve.

So 48 hours is not the moment your child stops being contagious. It is the point where the risk has dropped enough to be reasonable. That is worth knowing for two reasons. It explains why the clock runs from the last episode rather than from the day she started perking up. And it explains why handwashing at drop-off still matters on day three, day five, and day ten.

Getting her comfortably through those two days is its own job, and rehydration is most of it.

Clinical Mama Tip: Write the time, not the day, on the fridge. “Last vomit 9:15 p.m. Tuesday” tells you she can return Thursday evening, which means Friday morning. “Tuesday night” leaves you arguing with yourself at 6 a.m. about whether Thursday counts.

Coughs, Colds, and Runny Noses

Usually no exclusion at all, as long as she is fever free and well enough to take part in the day. Niagara’s guidance for the common cold is that a child stays home until fever free without medication, other symptoms have been improving for 24 hours, and no new symptoms have appeared.

A runny nose alone is not a reason to keep a child home. If it were, most Canadian toddlers would miss October through March.

Anything Needing Antibiotics First

For strep throat and impetigo, back after 24 full hours of the prescribed antibiotic, and well enough to participate. For pertussis, five days of appropriate antibiotics. Other infections carry their own periods, so ask which one applies to the specific diagnosis.

The word “and” in that first sentence carries more weight than parents expect. Twenty-four hours of antibiotic clears the exclusion, but it does not automatically mean your child is ready for a full day in a busy room. Loose stools in the first few days of a course are common and are not a reason to keep her home, though they will look alarming to whoever is changing her. It is worth telling the centre she is on an antibiotic and what is normal in the first few days versus what needs a call, so nobody sends her home a second time for something the medication is causing.

Rashes

Rashes are their own category, because the return rule depends entirely on which rash it is. Some carry no exclusion at all. Four carry a real one. And in Alberta, AHS does not publish a rash table, which means the return date comes from a clinician rather than a list.

I have covered all of it separately in rashes in kids, and when they can go back to daycare, including the chickenpox question where even Canadian sources disagree with each other.

Where the 24-Hour Number Comes From

Search this question and you will get Children’s Health Dallas, Nationwide Children’s, Texas Children’s, HealthyChildren.org, and a stack of American parenting sites. Every one of them is competent. None of them is writing for you.

Those pages are built on American Academy of Pediatrics guidance, where the exclusion standard is vomiting two or more times in the previous 24 hours, and return after roughly 24 hours symptom free.

It is a defensible standard, and here is the part that surprised me: it happens to match what Quebec and Nova Scotia tell their families. So the problem is not that the American number is wrong. The problem is that it may or may not be yours, and nothing on those pages tells you which.

And Canada Does Not Have One Number Either

I want to be honest with you about something most posts on this topic would smooth over. When I went looking for the Canadian number, I did not find one.

Quebec is 24 hours. The Ministère de la Santé et des Services sociaux exclusion tool permits a return when the child has no fever, is well enough to take part in group activities, has had no vomiting in the last 24 hours, and has diarrhea contained in a diaper or is continent with no blood or mucus.

Nova Scotia is also 24 hours. The provincial guidelines exclude a child until they are symptom-free for at least 24 hours, and they allow a child with a single episode and no other signs of illness to come back the next day.

Alberta and Ontario are 48.

New Brunswick has no number at all for a single case of unexplained stomach illness. The rule there is that symptoms have stopped and the child is well enough to attend, with 48 hours applied only when there are two or more cases or when norovirus is suspected. British Columbia does not publish a number either.

So a family in Gatineau and a family in Ottawa, fifteen minutes apart, are working from different rules. A family in Halifax follows a different rule than a family in Calgary. None of them is wrong. Exclusion guidance is set provincially and delegated locally, which is exactly why a number pulled off the internet cannot be trusted to be yours, even when the site is Canadian.

Who Actually Decides

Four authorities have a say, and only some of them bind your centre.

1. Public health guidance recommends. Niagara, AHS, Ottawa Public Health, Waterloo. These units publish exclusion periods and they are the best evidence available. They are guidance to centres, not something a parent can enforce at the door.

2. Your centre’s written policy binds you. The handbook you signed at enrolment is the operative document. A centre may be more conservative than public health guidance, and many are, particularly with vomiting. If the handbook says 48 hours after symptoms resolve rather than after they improve, that difference is real and enforceable.

3. In Alberta, the licence holder decides. Covered above. No number in law.

4. An active outbreak overrides everything. Once a centre is in a declared outbreak, public health takes the wheel. Niagara’s outbreak protocol excludes symptomatic children until 48 hours symptom free, including fever free without medication for 24 hours before return. In Alberta, AHS can issue exclusion orders and require a clearance letter before a specific child returns.

When your centre is stricter than public health

This happens, and you are allowed to ask about it.

A centre may set a policy stricter than provincial guidance. If it is written into your enrolment agreement, you are likely bound by it regardless of what any health unit recommends.

What you can do is ask, in writing, what the policy is based on. Some centre policies were written years ago from American reference material and have never been revisited. A director looking at current provincial guidance may update it, particularly if more than one family raises it.

What tends not to work is arguing at pickup with a phone in your hand. Send an email, name the source, ask calmly, and accept that the centre may keep its policy. Some of them are deliberately cautious, which is their call to make.

Clinical Mama Tip: Ask for the illness policy in writing at enrolment, before anyone is sick. “Can I get a copy of your exclusion policy?” is a boring question in September and an emotionally loaded one at 6:40 a.m. on a Thursday. Ask it in September.

The Doctor’s Note Question

Most of the time, a note is the wrong tool.

The Ontario Medical Association’s position is that notes written purely to clear someone to return to work or school are not an appropriate use of primary care resources, and Ontario’s Ministry of Health has recommended against requiring them. Sitting in a walk-in for three hours with a recovered child, to obtain a piece of paper saying she seems fine, helps nobody and exposes her to whatever else is in that waiting room.

But in Alberta, there is a line worth knowing

The same regulation that gives the operator discretion also contains an override. The exclusion requirement does not apply if the parent provides written notice from a physician indicating that the child does not pose a health risk to people on the premises.

Notice what that switches off. The subsection it disapplies covers both sending the child home and keeping her out. So a note already on file does not shorten an exclusion. It means the exclusion provision does not apply in the first place.

That is a genuine legal off-ramp, and almost no parent knows it exists.

One detail matters here. The regulation says physician. A note from a nurse practitioner may well satisfy your centre, since the licence holder only has to be satisfied that your child is not a health risk. But it is a physician’s note that removes the requirement as a matter of law. Worth knowing if your family’s primary care runs through an NP, which is increasingly common in Alberta.

I am not telling you to go collect notes. Most of the time you will not need one and should not seek one. But it matters in a narrow set of situations:

• Your child has a chronic, non-infectious cause for a symptom that keeps triggering exclusion. Reflux, teething-related loose stools, a chronic cough
• The centre and your physician genuinely disagree about whether she is still contagious
• She has been excluded repeatedly for something that is not transmissible

In those cases, a note is not paperwork theatre. It is the mechanism the regulation actually provides.

Clinical Mama Tip: If you do need a note for a recurring, non-infectious issue, ask for it to name the condition and state that it does not pose a health risk to others. A note that only says “seen in clinic today” does not do what the regulation asks for.

What to Say When You Call the Centre

Have the conversation before drop-off, not in the doorway with your coat on and a child on your hip.

If symptoms have resolved and you agree with the policy:

“Hi, it’s Oyinda, Ada’s mom. Her last episode of vomiting was Tuesday at 9:15 p.m. She’s eaten normally since yesterday morning and she’s been fever free without any medication. That puts her past 48 hours as of last night. Is she clear to come in tomorrow?”

Specific times. No hedging. You are giving them what they need to say yes. Swap in whatever period your province or your centre uses.

If the centre is stricter than public health guidance:

“I want to make sure I understand the policy so I can plan. Public health here says 48 hours after symptoms improve, and I’m reading the handbook as 48 hours after they fully resolve. Can you confirm which one you’re applying so I know when to book coverage?”

You are not arguing. You are asking her to state the rule clearly, which is reasonable and which she can do.

If you think the rule is being applied unevenly:

“I’d like to understand the reasoning here, because I want to be consistent with it. What specifically are you looking for before she can come back?”

That question is hard to answer vaguely, and it is not confrontational. Most of the time the answer is reasonable and you will simply learn something about the policy. Occasionally it surfaces that the decision was made on a hunch, and asking calmly is the fastest route to a second look.

Red Flags: When This Stops Being About Daycare

Everything above assumes a child who is recovering. Some situations are not about the exclusion period at all, and I would rather you close this page and act.

Go in or call for urgent advice if:

• Your baby is under three months old and has a fever
• You see signs of dehydration: no wet diaper in six to eight hours, no tears when crying, a dry mouth, sunken eyes, or unusual sleepiness and difficulty waking
• There is blood in the stool or the vomit
• Vomiting is persistent enough that she cannot keep any fluid down
• She is getting worse rather than better, or a fever has come back after breaking
• She has severe or constant stomach pain
• Something feels wrong to you in a way you cannot name

That last one is not filler. You know your child’s baseline better than any guideline does.

In Alberta, Health Link at 811 will talk you through it, day or night, and can tell you whether this needs a clinic, an emergency department, or a wait-and-watch. Most provinces have an equivalent line.

Province by Province

The provinces below cover most of the country by population. If yours is not here, the pattern still holds: find your provincial health authority or regional public health unit, search its name plus “child care exclusion,” and use that page rather than a general one.

Alberta

Stomach illness: 48 hours after the last episode of vomiting or diarrhea, per Alberta Health Services.

Fever and respiratory illness: fever free for 24 hours with symptoms improved.

Rashes: no published table. AHS directs families to stay home for the length of time recommended by a physician, nurse practitioner, or the AHS Public Health Outbreak team.

The catch: the Early Learning and Child Care Regulation sets no number at all and leaves the return decision to the licence holder. A physician’s note is a formal override, and the regulation names a physician specifically, not a nurse practitioner.

Ontario

Stomach illness: 48 hours. Niagara, Wellington-Dufferin-Guelph, Huron Perth, Waterloo, Peel, and Ottawa Public Health all publish the same period.

Fever and colds: fever free without fever-reducing medication and other symptoms improving for 24 hours.

The catch: guidance is delegated to your local public health unit, and outbreak rules tighten the standard from “improving” to “fully resolved.” Check your own unit rather than the province.

Quebec

Stomach illness: the provincial exclusion tool permits return with no vomiting in the last 24 hours, stools contained in a diaper or the child continent, and no blood or mucus.

General condition: no fever, and well enough to take part in group activities.

Nova Scotia

Stomach illness: 24 hours symptom-free. A single episode of vomiting or diarrhea with no other signs of illness allows a return the next day.

Fever: a child under six months with any fever goes home and should be seen by a provider. Over six months, fever plus another symptom or a behaviour change is the trigger.

The catch: the Medical Officer of Health has statutory authority to exclude a child and to decide when that child returns, which overrides the general guidance.

British Columbia

BC does not publish a condition-by-condition table for parents. The BCCDC position is that a child returns once they feel well enough to take part in regular activities and no longer have a fever or symptoms, while noting that some illnesses, gastrointestinal illness caused by norovirus among them, may mean staying home longer. In practice that means your centre’s policy is doing most of the work in BC, so read it.

New Brunswick

New Brunswick publishes the clearest exclusion table in the country, in the Guidelines for the Prevention and Control of Communicable Diseases in Early Learning and Childcare Facilities, updated May 2026. Appendix B is a plain two-column list. If you are in New Brunswick, ask your centre for it.

Stomach illness, one child, cause unknown: no fixed number. Exclude until symptom free, meaning diarrhea, vomiting and fever have stopped, and the child is well enough to attend. If norovirus is strongly suspected, the operator may extend that to 48 hours after consulting public health.

Stomach illness, two or more cases: 48 hours symptom free, or as directed by public health.

Diagnosed norovirus, rotavirus, or salmonella: 48 hours symptom free.

Fever from an unspecified cause: fever free for 24 hours without fever-reducing medicine.

Chickenpox: until the child feels well enough to return. New Brunswick does not require the blisters to crust over.

The catch, and it is unique to New Brunswick: most exclusions require a Return After Exclusion Form before the child comes back. For E. coli, shigella, and typhoid, a public health signature is required on top of that. Parents also have to notify the operator within 24 hours of a confirmed diagnosis. So New Brunswick pairs the clearest published rules with the most paperwork, and knowing the form exists saves you a surprise at the door.

If your province is not listed

I did not include Saskatchewan, Manitoba, Prince Edward Island, or Newfoundland and Labrador, because I could not find current parent-facing exclusion guidance published for them. That absence is itself worth knowing. It does not mean there is no rule. It means the rule lives in your centre’s policy and in your regional health authority rather than on a page you can easily find, so those are the two places to ask.

This post reflects guidance published by Alberta Health Services, several Ontario public health units, Quebec’s Ministère de la Santé et des Services sociaux, Nova Scotia’s Department of Health and Wellness, Public Health New Brunswick, and the BC Centre for Disease Control as of the review date above, plus Alberta’s Early Learning and Child Care Regulation. Exclusion rules vary by province and by centre, and they change. Your daycare’s own policy governs your child’s return.

A Quick Reference: The Rules Worth Saving

• Vomiting or diarrhea: 48 hours in Alberta and Ontario, 24 in Quebec and Nova Scotia, no set number in BC or New Brunswick
• Fever: 24 hours fever free, with no acetaminophen or ibuprofen in that window
• Runny nose alone: usually no exclusion
• Strep, impetigo, bacterial pink eye: 24 full hours of antibiotic
• Rashes have their own rules, and in Alberta the return date comes from a clinician
• Write the time of the last episode, not the day
• Your centre’s written policy is what binds you, not the guidance you found online
• In Alberta, the licence holder decides, and a physician’s note is a formal override (the regulation says physician, not nurse practitioner)
• During a declared outbreak, public health overrides everything
• Ask for the illness policy in September, not in the doorway

Clinical Mama Takeaway

The morning I described at the top ended with me keeping her home a fourth day, because I could not get a straight answer fast enough. She was fine. I lost a shift I could not afford to lose.

What I did not understand then is that there was no straight answer to find. Not because the information is hidden, but because in Alberta the decision genuinely belongs to a person rather than a rule. Once you know that, the whole thing gets easier. You stop hunting for a regulation to cite and start giving the decision-maker what she needs.

Times, not days. Symptoms, not impressions. Medication history, stated plainly.

And read the policy in September, when nobody is sick and nobody is upset. That one habit prevents most of these mornings.
