Burger King’s main vegan-friendly order in Canada is the Impossible Whopper, ordered without mayo. As the restaurant normally serves it, the burger is vegetarian but not vegan, because the standard build includes egg-based mayonnaise. It is also prepared on the same cooking surfaces as beef products, which matters to many vegans and to anyone managing a food allergy.
This guide covers what you can realistically order, how to order it, and which details you should confirm before you go. Where a fact could not be verified for Canada, the article says so instead of guessing.
Quick Answer: What Is Vegan at Burger King Canada?
- Impossible Whopper, no mayo: the best-known vegan-friendly order. The patty is plant-based, and the mayo is the main animal-derived ingredient to remove.
- Veggie Burger, no mayo: one dairy-free and vegan guide lists this as a Canada-only item. It could not be confirmed on Burger King’s own Canadian menu, so check your restaurant or the app first.
- French fries and onion rings: vegan guides commonly list these as free of animal-derived ingredients, but much of that information comes from U.S. sources. Check the Canadian ingredient details before ordering.
- Not vegan by default: the standard Impossible Whopper (with mayo), anything with cheese, and the meat items.
Treat everything here as “vegan-friendly,” not “certified vegan.” No source found for this article shows Burger King Canada certifying any menu item as vegan.
| Item | Vegan as normally served? | What to do |
|---|---|---|
| Impossible Whopper | No (egg-based mayo) | Order with no mayo |
| Veggie Burger | Not confirmed for Canada | Ask the restaurant; order with no mayo |
| French fries | Not confirmed for Canada | Check Canadian ingredient information |
| Onion rings | Not confirmed for Canada | Check Canadian ingredient information |
| Cheese and meat items | No | Skip |
Is the Impossible Whopper Vegan in Canada?
The patty is plant-based. The finished burger is a different question, and the answer depends on how you order it and how strict you are.
The Mayo Is the Main Issue
Burger King Canada built the Impossible Whopper like its beef version, with tomatoes, onions, lettuce, pickles, ketchup and mayonnaise on a sesame seed bun. Coverage at the Canadian launch described the mayo as egg-based and noted it can be left off. That is why “no mayo” is the standard vegan-friendly request.
Shared Cooking Surfaces
Canadian trade coverage reported that the Impossible Whopper is cooked on the same surfaces as Burger King’s meat products. Launch coverage also noted that Burger King does not describe the burger as entirely plant-based for that reason.
If you avoid animal products for ethical reasons, you will need to decide whether cross-contact is a dealbreaker. Some U.S. vegan guides suggest asking for an alternative preparation method. Whether a Canadian restaurant can or will do that is up to the location, so ask politely and do not count on it.
The Bun and Other Ingredients
The sesame seed bun contains wheat and sesame according to allergen listings. We could not verify whether the current Canadian bun, ketchup or pickles contain any animal-derived ingredient. A recent U.S. review also reported that Burger King changed its bun and mayo in 2026, which is a reminder that recipes shift. Check current Canadian ingredient information rather than relying on an older guide, including this one.
How to Order the Impossible Whopper Vegan-Friendly
- Check the ingredient details first. Restaurant Brands International says nutrition, allergen and ingredient information is available through the online ordering experience in Canada and the U.S. Use the Burger King Canada website or app before you order.
- Ask for “Impossible Whopper, no mayo.” If the app offers a customization option for removing mayo, use it.
- Mention that you want no mayo again at pickup. Busy orders can go wrong, so look at the burger before you leave the counter or drive-thru.
- Choose your sides carefully. See the next section.
- Say so if cross-contact matters to you. The staff can tell you what the location is able to do.
Sides, Breakfast and Desserts
Fries and Onion Rings
Dairy-free and vegan guides list fries and onion rings as free of animal-derived ingredients, and the guide we reviewed covers both Canada and the U.S. Its main detail, however, is for U.S. restaurants. Confirm the Canadian ingredient list. Shared fryers were also not verified, so strict vegans should ask the restaurant.
Breakfast
U.S. vegan guides often name hash browns and French toast sticks as vegan-friendly breakfast items. Burger King Canada’s breakfast menu is not identical to the U.S. menu, and we did not verify these items for Canada. Do not assume they are available or vegan here.
Desserts and Shakes
No Canadian vegan information was verified for desserts, shakes or frozen treats. Many of these items commonly contain dairy, so check the ingredient details before ordering.
Allergen and Dietary Notes
- Soy: the Impossible patty is soy-based.
- Wheat and sesame: both are present in the sesame seed bun.
- Egg: standard mayo contains egg.
- Milk: sources disagree. One third-party allergen listing says the sauce contains milk, while another says the burger does not contain milk. Check Burger King’s official allergen information.
- Gluten: the burger is not gluten-free because of the bun.
- Serious allergies: because of shared cooking surfaces and ingredient changes, do not treat this burger as safe for a severe allergy without official confirmation from Burger King Canada.
Vegan, Vegetarian and Plant-Based: What They Mean Here
- Plant-based describes the patty’s ingredients. It does not guarantee the finished sandwich is vegan.
- Vegetarian generally allows egg and dairy, so the standard Impossible Whopper fits for many vegetarians.
- Vegan excludes all animal-derived ingredients, and many vegans also consider cross-contact. That is why the order and the cooking method both matter.
How the Impossible Whopper Arrived in Canada
Burger King and Impossible Foods announced the Canadian launch in March 2021. The burger began at participating Ontario restaurants on March 22, 2021, with a cross-Canada rollout on April 12, 2021. Burger King described itself as the first quick-service restaurant in Canada to offer the Impossible Foods patty nationwide. Availability is at participating restaurants, so confirm with your local location.
What About Prices?
Prices were not published in this article because current Canadian prices could not be verified from an official source on October 27, 2026. Prices vary by restaurant, province, delivery platform and promotion, and a combo costs more than the burger alone. Use the Burger King Canada app or website for the price at your location.
