A pet vaccine certificate is a document signed by a veterinarian that identifies your pet and records which vaccine was given, when, and when the next one is due. In Ontario, the rabies certificate is the one the law spells out: Regulation 567 lists thirteen things it must contain, from your pet's microchip number to the vaccine's serial number and the reimmunization date.
You'll get asked for it more than you'd think. Kennels, groomers, daycares, landlords, border officials and public health units can all want to see one, usually at short notice.
Here's what a valid certificate holds, how it's different from an invoice or a reminder card, and how to keep yours where you can find it.
What does a pet vaccine certificate show?
A pet vaccine certificate shows who your pet is, who vaccinated them, with what, and when they're due again. Ontario's Regulation 567 under the Health Protection and Promotion Act sets out what a rabies certificate must contain, and it makes a good model for any vaccine record. Section 6 says the certificate has to be signed by the veterinarian who gave the vaccine, or who authorized the delegate who gave it, and must contain:
| About | Required details |
|---|---|
| You | Name and address of the owner or person caring for the pet |
| Your pet | Species, breed, colour, sex, age and name; any markings; approximate size |
| Identification | Any microchip number, tattoo number or other permanent ID |
| The clinic and vet | Address where the pet was immunized; the vet's full name and contact information |
| The vaccine | Name and serial number of the vaccine; the reimmunization interval in its product monograph |
| The dates | Date of immunization; whether it was a primary or booster dose; the date by which the pet must be reimmunized |
| The tag | The identification number on the rabies tag, for a cat, dog or ferret |
No vet's signature, no vaccine serial number and no due date? Then it's probably not a vaccine certificate.
The rabies certificate in Ontario
Rabies is the one vaccine Ontario law requires. Under Regulation 567, every owner or person caring for a cat, dog or ferret three months of age or over has to make sure the pet is immunized against rabies, and has to get them reimmunized by the date on the certificate.
The shot can be given by a veterinarian authorized to practise in Canada or the United States, or by their lawful delegate, using a rabies vaccine licensed where it's given. You walk out with a certificate of immunization and, for a cat, dog or ferret, a rabies identification tag.
Some pets can't be vaccinated safely. In that case a vet can issue a signed statement of exemption that records the medical reason and any past rabies doses, and the pet has to be kept away from possible rabies exposure.
The City of Toronto reminds owners to keep a copy of the vet-issued certificate at all times. Our guide to proof of rabies vaccination for daycare and boarding covers what those businesses usually check.
Certificate, invoice or reminder card: what is the difference?
An invoice proves you paid for a visit; a certificate proves what was given, and it's signed to say so. You often leave a vaccine appointment holding three or four papers, and they're easy to mix up.
| Document | What it is for | Usually accepted as proof? |
|---|---|---|
| Signed vaccine certificate | Official record of the vaccine, dose type and due date | Yes |
| Invoice or receipt | A bill for services; may list a vaccine by name | Often not, as it lacks the serial number, signature and due date |
| Reminder postcard or email | Tells you a vaccine is due | No |
| Full medical record | The clinic's chart, with every visit and note | Sometimes, but it holds far more than most people need to see |
| Rabies tag | Links your pet to its certificate by number | Not on its own |
Kennel turned away your invoice? Call your clinic and ask for the vaccine certificate; most can email it the same day. You've got a right to copies of your pet's records, which we cover in who owns your pet's medical records.
Who asks for a vaccine certificate?
Boarding kennels, daycares and groomers ask most often, to protect the other pets in their care. Each one sets its own list, so check before you book.
Public health gets involved after a bite. Ontario's rules require bites to be reported to the medical officer of health, and your pet's rabies status shapes what happens next.
At the border, the Canadian Food Inspection Agency's import rules ask that dogs eight months or older from countries not free of rabies, and cats three months or older, arrive with a veterinarian's certificate in English or French that clearly identifies the animal and shows current rabies vaccination.
Landlords, condo boards and some training classes may want proof before a pet moves in or signs up. And a new vet will want the whole history, not just the certificate.
Dog vaccination certificate and cat vaccine record
Dogs and cats get different vaccines, but the certificate works the same way: one line per vaccine, each with its date, its serial number and when it's due again. Which ones your pet needs depends on age, health and lifestyle, so ask your vet. Our dog and cat vaccine schedule for Canada explains the usual timing.
Take thirty seconds at the counter before you leave. Is your pet's name spelled right? Is the microchip number correct? Is the due date filled in? One wrong microchip digit can cause real trouble at a border.
How to keep your certificates ready
Keeping certificates ready is mostly a habit. Ask for the certificate, not just the invoice, at every vaccine visit. Snap a photo or scan it the day you get it. File the paper original with your pet's passport, microchip papers and adoption papers, and put the due date somewhere you'll actually see it.
In the free PetGrid app you can upload the paper to your pet's records, and AI record reading can suggest the vaccines it finds for you to confirm. The app's vaccine card is a PDF of the vaccines you keep in the app, with an optional QR code a groomer or kennel can scan. It's a handy summary marked as added by you, not a vet-signed certificate, so hang on to the original for anyone who needs the signed version.
Questions people ask
How do I get a copy of my pet's vaccine certificate?
Ask the clinic that gave the vaccine. Most can email or print a copy quickly, and you're entitled to copies of your pet's records.
Is a vet invoice proof of vaccination?
Usually not. An invoice is a bill and normally lacks the vet's signature, the vaccine serial number and the due date that a certificate carries, so many kennels and border officials won't accept it.
What must a rabies certificate include in Ontario?
Ontario's Regulation 567 lists thirteen items. They include the owner's name and address, the pet's description and microchip number, the vet's name and contact details, the vaccine name and serial number, the date given, whether it was a primary or booster dose, the due date and the rabies tag number.
Does my indoor cat need a rabies certificate in Ontario?
Yes, Ontario law requires every cat, dog and ferret three months of age or over to be immunized against rabies, indoor or not. A vet can issue a statement of exemption only when a medical condition makes vaccination unsafe.
Can I show a digital copy of my pet's vaccine certificate?
Many kennels and groomers accept a clear photo or PDF, but each business sets its own rules. Border officials and some others may want the signed original, so bring it when you travel.
The short version
So: the pet vaccine certificate is the vet-signed paper that names your pet, the vaccine, its serial number and the next due date. Ask for it every time, check it at the counter, and keep both the original and a copy.
The free PetGrid app holds a copy of each certificate with your pet's records, sets reminders for the due dates, and makes a vaccine card you can share in seconds.
Keep your pet's records, vaccines and visits in one safe place. The PetGrid app is free for pet owners, with or without a clinic.
