Pet Microchip Data When Moving From Canada: 2026

Why Canadian Microchip Registries Create International Gaps

A pet microchip stores only a unique identification number. All owner contact details, addresses, and veterinary records are held separately in registry databases. Canada does not operate a unified national microchip registry. Instead, data is split across provincial systems and private databases such as 24PetWatch, BC Pet Registry (operated by the BC SPCA), and EIDAP. None of these registries automatically share data with foreign databases.

When a Canadian pet goes missing abroad, a veterinarian or shelter in the destination country will scan the chip and retrieve the ID number. If that number is only registered in a Canadian database, the foreign clinic may have no way to contact the owner. Professional pet relocation specialists consistently flag this registry gap as one of the most overlooked steps for Canadians moving internationally.

Province by Province: Microchip Rules Across Canada

Microchip legislation in Canada is set at the provincial and municipal level, not federally. Here is a summary of major jurisdictions:

• British Columbia: Requires permanent pet identification in the form of a microchip or tattoo. Vancouver mandates microchipping as a prerequisite for dog licensing. The BC Pet Registry (bcpetregistry.ca), a non-profit operated by the BC SPCA, serves as the province's primary database and is internationally traceable.
• Alberta: Calgary requires microchipping for all dogs and cats. Edmonton and other municipalities have their own bylaws. Alberta Animal Health Source provides provincial guidance on pet identification standards.
• Ontario: Toronto mandates microchipping for dogs and cats adopted from city-operated shelters. Provincial legislation does not currently require universal microchipping, though many municipalities encourage it.
• Quebec: Montreal requires microchipping for dogs. Provincial regulations are evolving, and owners should verify municipal bylaws before travel.

Regardless of local bylaws, the Canadian Veterinary Medical Association (CVMA) recommends microchipping as a standard of care for all companion animals.

ISO vs Non ISO Chips: What Canadian Owners Need to Check

Most microchips implanted by Canadian veterinary clinics in recent years are ISO 11784/11785 compliant (134.2 kHz, 15 digit numeric code). However, some older chips, particularly those implanted before 2010, may use non-ISO frequencies (125 kHz or 128 kHz) or shorter alphanumeric codes.

How to Verify Your Pet's Chip

1. Find the chip number. Check your pet's vaccination booklet, your registry account on 24PetWatch or BC Pet Registry, or ask your veterinarian to scan your pet at the next visit.
2. Count the digits. A 15 digit numeric code typically confirms ISO compliance. A 9 or 10 character alphanumeric code suggests a non-ISO chip.
3. Confirm the frequency. Your veterinarian can verify whether the chip broadcasts at 134.2 kHz using a universal scanner.
4. If non-ISO, implant a second chip. Pets can safely carry two microchips. A second ISO chip can be implanted alongside the original without interference. This is routine veterinary practice and typically costs between $50 and $80 CAD.
5. Timing is critical. For destinations that require rabies vaccination linked to the microchip (including the EU, UK, and Australia), the ISO chip must be implanted before the rabies vaccine is administered. Reversing this order can invalidate the vaccination certificate for entry purposes.

CFIA Export Requirements: Getting Your Pet Out of Canada

The Canadian Food Inspection Agency (CFIA) oversees the export of companion animals. For most international destinations, you will need:

• An export health certificate issued by a CFIA-accredited veterinarian and endorsed by a CFIA official veterinarian
• A valid rabies vaccination certificate with the microchip number recorded
• Destination-specific documentation (the EU, for example, requires an Animal Health Certificate with specific formatting)

CFIA district offices across the country can advise on destination-specific requirements. Processing times for export certificates vary, so veterinary guidelines suggest beginning the process at least 8 to 12 weeks before your departure date.

Crossing the US Border: The 2024 CDC Rule Change

For the millions of Canadians who travel to the United States with their dogs each year (including seasonal snowbirds heading south for the winter), the August 2024 CDC rule change is significant:

• All dogs entering the US must carry a microchip readable by a universal scanner.
• Dogs must be at least six months old.
• Owners must complete the online CDC Dog Import Form and present the receipt at the border.
• Canada is classified as a dog-rabies-free or low-risk country, which means dogs from Canada can enter at any US airport, seaport, or land border crossing.
• The CDC accepts any universally readable microchip; an ISO-specific chip is not required for US entry, but an ISO chip is strongly recommended for broader international compatibility.

This is especially relevant for Canadians who drive across the border for winter stays in warmer US states. Ensure the microchip is registered and your contact information is current before every trip.

Canadian Microchip Registries and International Lookup Tools

Canadian Registries

• 24PetWatch (24petwatch.com/ca): North America's largest pet microchip registry with over 30 million pets registered. Operates across Canada and the United States, which provides some cross-border coverage.
• BC Pet Registry (bcpetregistry.ca): British Columbia's permanent pet ID database, operated by the BC SPCA. Offers internationally traceable microchip registration.
• EIDAP (eidap.com): Electronic Identification Devices for Animals and Plants. A Canadian microchip distributor that maintains its own registry.

International Aggregator Tools

• PetMaxx (petmaxx.com): Searches more than 32 international registries simultaneously. Free for lookups and essential for cross-border recovery.
• Europetnet (europetnet.org): Connects approximately 35 European national databases. Critical if relocating to an EU member state.
• WorldPetNet (worldpetnet.com): International registry with global database linking. Offers both registration and search functions.
• AAHA Universal Microchip Lookup (aaha.org/microchip): Searches participating North American databases. Useful for identifying which registry holds your chip's data.

Step by Step: Transferring Your Microchip Data Internationally

Before Leaving Canada (8 to 12 Weeks Out)

• Log into your Canadian registry (24PetWatch, BC Pet Registry, or other) and update your phone number to one that will remain active internationally. Add a Canadian emergency contact who can be reached if your pet is found.
• Do not cancel your Canadian registration. Keeping it active provides a backup if someone searches Canadian databases.
• Download or print your registration confirmation. Some countries require proof that the microchip is registered to you.
• Register with an international aggregator such as PetMaxx or WorldPetNet to maximise cross-border visibility.

After Arriving at Your Destination (First Two Weeks)

• Visit a local veterinarian to confirm the chip is readable with local scanning equipment.
• Register your chip number with the destination country's national microchip database.
• Update both your Canadian and destination registries with your new local phone number.

Canadian Climate and Seasonal Travel Considerations

Canada's extreme climate creates unique timing considerations for international pet relocation:

• Winter departures: Temperatures can drop below minus 30°C in much of the country between December and February. Airline pet cargo restrictions often apply when ground temperatures fall below minus 12°C, which can delay travel plans. Build extra buffer time into your schedule.
• Summer travel: Eastern Canada experiences hot, humid summers. Airlines also restrict pet cargo when temperatures exceed 29°C on the tarmac. The safest windows for air travel with pets are typically spring (April to May) and autumn (September to October).
• Snowbird season: Canadians heading to the southern US for winter should update their microchip registries before each trip, not just the first time. Contact details change, and registry accounts can lapse. Review Heatstroke in Dogs: Cooling Protocols and Breed Risks before arriving in warmer climates.

Common Mistakes Canadian Pet Owners Make

• Assuming the chip stores your contact info. The chip holds only a number. All details live in a separate database. If that database is inaccessible abroad, the chip is effectively anonymous.
• Deleting the Canadian registration. Keep both your Canadian and destination country registrations active. Dual registration increases recovery chances through either a local or international search.
• Discovering a non-ISO chip at the airport. Many owners only learn their chip is incompatible at the departure gate or at the destination quarantine facility. Verify compatibility months before travel.
• Forgetting the CDC form for US trips. Since August 2024, the online CDC Dog Import Form is mandatory for all dogs entering the United States. Arriving at the border without the receipt can result in your dog being denied entry.
• Not updating after domestic moves. Moving from one Canadian province to another without updating your registry is just as risky as moving internationally. Provincial databases do not automatically sync.

Ongoing Microchip Maintenance

• Annual veterinary visits: Ask your veterinarian to scan the chip at every routine appointment to confirm it remains functional and readable. Chips can occasionally migrate or fail.
• Change of address: Update your registry every time you move, whether across provinces or across countries.
• Senior pets: Older pets may carry chips implanted before ISO standards became common in Canada. If planning international travel with a senior pet, verify the chip type well in advance. For more guidance, see Senior Pet Care.
