Flying with a service dog in Canada

Federal transportation — air, and the interprovincial rail, ferry and bus services the same regulation covers — is the one place in Canada where a single, national, written definition of a service dog applies, and it is stricter than most provincial definitions. It is also one of the few places where a specific document is expressly contemplated by the rules, and that document is not a registry card. This page sets out what the regulation says, what the airlines add on top of it, and where the two most common assumptions go wrong: that your dog qualifies because it qualifies at home, and that the flight is always free.

What to carry

Start with your ServDog registration, because it is where the answers to the airline's form already live: who trained the dog, what it is trained to do, and since when, all dated as it happened. The airline's declaration asks you to attest to exactly that, and the honest answer is far easier to give from a record you kept than from memory at a check-in desk. Your trainer's details, your provincial card if you hold one, and your vet's records sit in the same account, so the form is a matter of attaching what is already there. Have the card on your phone too — it lives in your wallet app, or print it if you prefer paper. At a gate, a card that says the dog is registered, that its training is on record and what it does is a shorter conversation than a vest alone. What the card is not is the trainer-issued document the regulation describes below — say so when you hand it over, and attach the trainer's paperwork alongside it.

Who the rules apply to

The federal rules are the Accessible Transportation for Persons with Disabilities Regulations, SOR/2019-244 — the ATPDR. Section 25 applies the relevant part to "every large air carrier that provides a service for the transportation of passengers" on flights "between points within Canada," "from a point of origin in Canada to a point of destination in a foreign country," and "from a point of origin in a foreign country to a point of destination in Canada."

A large air carrier, under s.25(2), "means an air carrier that transported a worldwide total of 1,000,000 passengers or more during each of the two preceding calendar years." The national airlines are in; many regional and northern operators are not.

Smaller carriers are not a free-for-all. The Canadian Transportation Agency's guide says: "Transportation service providers not covered by the ATPDR still have obligations regarding the transportation of service dogs." Those obligations come from the Agency's general accessibility jurisdiction and the carrier's own tariff, and you should read that tariff before you book.

What counts as a service dog in the air

Section 1 of the ATPDR defines a service dog as:

"a dog that has been individually trained by an organization or person specializing in service dog training to perform a task to assist a person with a disability with a need related to their disability."

Two elements, both required: a trained task, and a trainer who specialises in service dog training. This is the definition we discuss at length on the tasks page, and the second element is the one that catches owner-trained teams. A dog that is unquestionably a service animal in an Ontario restaurant may not meet this definition at Pearson.

Emotional support animals are not service dogs under the ATPDR. They are dealt with separately, below.

What the airline may ask for

Section 51(1) obliges a carrier, "on the request of a person with a disability who needs to travel with a service dog," to "accept the service dog for transport" and permit it to accompany the person on board. Section 51(2) then sets out what the carrier may require in return — that you "control the dog with a leash, tether or harness during travel," and that you provide:

• at the time of reservation, "a declaration attesting that the service dog has been individually trained by an organization or person specializing in service dog training to perform a task to assist the person with a disability with a need related to their disability"; and
• before departure, "an identification card or other document that is issued by an organization or person specializing in service dog training that identifies the person with a disability and attests that the service dog has been individually trained by the organization or person to perform a task to assist the person with a disability with a need related to their disability."

Read the second one carefully. The document is issued by the trainer. It identifies you. It attests to the training. A card from a registry — including ours — is not issued by the organisation that trained your dog and does not meet this description. Where your province issues a card after assessing the team, as Alberta, British Columbia and Nova Scotia do, that card is issued by government, not by your trainer, so it does not fit the s.51(2)(b) wording either — ask the airline in writing whether it will accept it. Air Canada's own form reproduces the s.51(2)(b) wording and asks you to attach a document meeting it.

Section 51(3) says the document condition is met if you provided the card or document for an earlier request and the carrier kept an electronic copy of it — so you should not have to produce it again, but only where the airline still has it on file.

The document, exactly

The regulation does not prescribe a form. What it describes, in s.51(2)(b), is "an identification card or other document that is issued by an organization or person specializing in service dog training that identifies the person with a disability and attests that the service dog has been individually trained by the organization or person to perform a task to assist the person with a disability with a need related to their disability." A letter on the trainer's letterhead does it. So does a card the trainer issues. What matters is who issues it and what it says.

In Tinkess v Air Canada, Decision No. 90-AT-A-2022, the Agency said what it expects to see. A handler "would be expected to file information such as": "an identification card or other document issued by an organization or person specializing in service dog training that identifies both the person with a disability and their service dog," and, for a dog that is not a guide dog, an attestation by that trainer covering four things —

• that "the service dog has been individually trained by that organization or person to perform a task or tasks to assist the person with a disability with a need related to their disability";
• "a clear description of the task(s) the dog has been individually trained to perform to assist the person with their disability-related need(s)";
• "the credentials of the trainer(s), including any qualifications, certifications and affiliations with professional service dog organizations such as Canadian Association of Service Dog Trainers and the Canadian Association of Guide & Assistance Dog Schools"; and
• "a clear description of the specific content of the training program(s) completed by the dog, including the duration of the program, the goals to be achieved by the dog, the involvement of the handler, the assessment methods used and the assessment results achieved by the dog and its handler."

Who can issue it. Any "organization or person specializing in service dog training." Nobody licenses that in Canada; there is no list and no badge. A school accredited by Assistance Dogs International or the International Guide Dog Federation plainly qualifies, and so does an independent professional whose work is service dog training. What the Agency weighs is evidence of specialisation and of having trained this dog. In Tinkess the handler produced a "Registered service/support animal card" and a "Service/support animal registration certificate" from an online vendor, and the Agency gave them no weight: there was no evidence the vendor "had any expertise in service dog training or that it had provided any training to the dog." That is the difference between a trainer's attestation and a registry card, ours included, stated by the tribunal that decides these cases.

If you trained your own dog. You cannot issue this document to yourself unless you specialise in service dog training. The route is a professional who worked with you — who coached the team, assessed it, and can honestly attest to the tasks and the program. Ask them for a letter with the four parts above; we have a template your trainer can complete. Keep the letter in your document store, and keep the Taskbook current, because it is the record the trainer's description of your program will be drawn from.

Notice: 48 hours, sometimes 96

Section 32(1): "If a person with a disability makes a request for a service set out in this Part at least 48 hours before the scheduled time of departure, the carrier must provide the service." Some services must be provided on shorter notice, but service dogs are not in that list, so the 48-hour rule governs. Section 32(3) removes that guarantee where you ask less than 96 hours before departure, the carrier tells you it needs "information or documents" to assess the request, and either you do not supply them within 48 hours or the carrier cannot finish its assessment in 48 hours because a non-business day falls in the way. Even then, s.32(4) says the carrier "must make every reasonable effort to provide" the service.

The Agency's guide puts it in one sentence: carriers may require "usually 48 hours notice in advance of departure but it can be as much as 96 hours if the carrier needs information or documentation relating to the service dog."

In practice: submit the airline's form when you book, not the week of travel.

Space on board

Section 51(4) deals with the large dog: "If, because of the size of the service dog, the passenger seat of the person with a disability does not provide sufficient floor space for the service dog to lie down," the carrier must provide whatever adjacent seating is needed for the dog to lie down. This is the section number to cite if you are told a second seat is unavailable — it is 51(4), not 51(3), and getting it right on the phone helps.

The Agency's guide notes one carve-out for ferries rather than aircraft: "If a marine carrier does not offer assigned passenger seats to passengers on a ferry, it is not obligated to provide adjacent seating."

Is it free? Inside Canada, yes. Across the border, not necessarily.

Section 31(1) prohibits a carrier from imposing "a fare or any other charge for any service that the carrier is required by this Part to provide." On a domestic flight, that covers the dog and the adjacent seat.

Section 31(2) is the part that gets left out of most summaries:

"The prohibition in subsection (1) does not apply to a carrier in respect of any service that the carrier is required to provide under section 50, 51 or 52 if that service is provided by the carrier for the purpose of a transportation service between Canada and a foreign country."

Section 51 is the service dog section. So on a flight between Canada and another country, the regulation does not stop the carrier from charging for services under s.51. The Agency's guide describes the effect narrowly — carriers are not prohibited "from imposing an additional fare or any other charge for an additional seat needed to accommodate a service dog when travel is between Canada and a foreign country" — but the regulation's own words are broader than the guide's example, and it is the regulation that binds. Ask the airline, in writing, what it charges before you book an international flight with a large dog.

For flights to the United States, US rules apply as well and add their own paperwork. That is a page of its own.

At the airport

Screening. CATSA's guidance: "All passengers travelling with animals, including service animals or guide dogs, must be swabbed for ETD testing" — explosive trace detection. "The screening officer will visually inspect your service animal or guide dog and its harness," and "You don't need to remove your service animal's or guide dog's harness but carrying bags or pouches must go through the X-ray and be swabbed." All of that guidance appears under CATSA's heading for blind or partially sighted passengers; CATSA publishes no separate general service-dog section. Expect the same approach for any service dog, but do not be surprised by variation. CATSA also says that "upon request, screening officers will expedite the security screening process for you," and — its own advice — "If you are travelling with a service animal or guide dog, contact your airline in advance to find out about related policies."

Relief areas. Section 227 requires the operators of larger airports (under s.212: those in a national or provincial capital, or with 200,000 or more passengers in each of the two preceding years) to provide designated relief areas for service dogs, "identified by tactile and Braille signage," "cleaned and maintained on a regular basis," with one reachable from the secure side of the terminal without exiting and re-entering. If you cannot find it, ask; it exists because the regulation says it must.

Dogs in training. The regulation does not cover them. The Agency says: "While the Regulations do not include service dogs in training, it is a good practice to accept dogs that are being trained by an organization or a person specializing in training service dogs." That is a recommendation to airlines, not a right you hold.

Behaviour. Section 51 says nothing about refusing a badly behaved dog; its only control provision is the leash requirement in s.51(2). What a carrier will do about a dog that is disruptive is in its tariff, and it is worth reading before you rely on the regulation alone.

Emotional support dogs

An emotional support animal is not a service dog under the ATPDR. In June 2023 the Agency issued Decision No. 105-AT-C-A-2023 after joining six applications brought against Air Canada, WestJet, Air Transat, KLM and VIA Rail. The Agency's own summary of the outcome is that "carriers are only required to accommodate dogs as ESAs," and it sets conditions, restated in its service dog guide, under which an emotional support dog is carried in the cabin:

• proof "from a physician or medical health professional that they are being treated for a mental health disability and that they require an emotional support dog";
• "at least 96 hours in advance of travel, a veterinary certificate identifying the dog and the person with a disability, and confirming the dog's current vaccination and health status," dated within two months of the first travel date;
• the dog "must fit comfortably in an appropriate animal carrier that must fit and be kept at the seat — or in the case of air travel, under the seat in front—of the person with a disability for the duration of the trip," and "must remain in the carrier for the duration of its time in the passenger cabin";
• the dog must meet "all travel, entry or exit requirements of the country, province, state or territory" travelled to or from; and
• a person travelling in compliance with these conditions "must not be charged."

What the decision does is state findings: that "it would not be undue hardship to require carriers to accept ESDs for carriage in the passenger cabin under the following conditions." It then severed the six applications so that each could be decided on its own facts, and it says in terms that it "has not addressed or made any decision regarding carrier policies on the carriage of pets." So the conditions are the Agency's stated position for the federal network; whether your airline carries emotional support dogs at all is set by that airline's policy — WestJet's page, for example, says it does not accept them in any cabin. Check with your airline before you book. A small dog in a carrier under the seat is, in any event, a very different trip from a service dog at your feet. Where ESA letters do and do not work in Canada.

The two national airlines

What follows is airline policy, not law, and airlines change their forms without notice. Check the current version on the airline's site before you travel.

Air Canada uses its own Service Dog Form for travel "within Canada, and to/from International and the Caribbean." The form asks that you "complete and submit this form to accessible@aircanada.ca at least 48 hours in advance of travel," and asks you to "include an identification card or other document that is issued by an organization or person specializing in service dog training" — the s.51(2)(b) wording. For the United States it uses a separate document, the U.S. Department of Transportation Service Animal Air Transportation Form.

WestJet states that it "only accepts dogs to provide services to persons with disabilities," and that "For domestic, international and Caribbean flights, service dogs must be individually trained by an organization or person specializing in service dog training." Its Service Dog Registration form asks for the training organisation's name, phone number and website, and is submitted to servicedog@contact.westjet.com. On notice, WestJet's page says: "we recommend that you request to travel with your service dog as soon as possible at least 48 hours before your flight departs," and that with less notice it "will make every reasonable effort to accommodate your request, which may include delaying you until another WestJet operated flight is available." Seven days for the United Kingdom or a WestJet Vacations package. It accepts one service dog per person, or two on an itinerary that touches the United States.

Coming home

A service dog returning to Canada from abroad is an import in the eyes of the Canadian Food Inspection Agency, and the paperwork it wants is on the United States travel page, which covers both directions.

What we do

The Taskbook has a field for who trained your dog and a dated entry for each task, because the s.51(2)(a) declaration asks you to attest to exactly that. Your document store holds the trainer's paperwork, your provincial card and the veterinary certificate an emotional support dog needs, so every form on this page is filled from one place.

We are not an organisation specialising in service dog training, and nothing we issue is the s.51(2)(b) document. What we hold is your own record of who trained the dog and what it was trained to do — the record you need to hand to sign the declaration honestly, and to show the airline alongside the trainer's letter.
