Cooking for someone with a food allergy takes extra care at every step, from the grocery aisle to the kitchen counter. This guide covers the basics of how Canadian food labels work. It does not replace advice from a health professional.
Know the priority allergens
Canada has a list of "priority allergens," the foods most often linked to severe allergic reactions. It includes common foods such as peanuts, tree nuts, milk, eggs, soy, wheat, sesame, fish, shellfish, and mustard, and Canadian labelling rules also cover sulphites and gluten sources. For the complete and current list, see the Government of Canada pages in our sources.
How labels work
According to the Canadian Food Inspection Agency (CFIA):
- Prepackaged foods that contain priority allergens and gluten sources must list them in the ingredient list, in a statement beginning with "Contains," or both.
- Some companies add "May contain" statements to warn of possible cross-contamination during manufacturing. These are voluntary.
- If a label has a "may contain" statement for your allergen, the CFIA advises assuming the allergen could be in the food and avoiding it.
- Always read the full ingredient list and any "may contain" statements.
- If your allergy is not a priority allergen, read ingredient lists carefully and contact the company if you are unsure.
Food Allergy Canada also recommends reading the label every single time you buy a product, since recipes can change.
Shopping tips
- Read the label on every purchase, including products you have bought before.
- Avoid bulk bins. Health Canada notes they may not have ingredient lists and carry a risk of cross-contamination between bins.
- Call the company if you are unsure about a product.
- Be careful with substitutes. Many substitutes contain allergens themselves, such as soy milk or almond milk, so check those labels too.
In the kitchen
Cross-contamination happens when an allergen is unintentionally transferred to food that does not normally contain it. Common household precautions include washing hands, using clean utensils, cutting boards, and pans, and cooking the allergy-safe meal first. Ask your allergist for guidance specific to your family.
Planning allergy-friendly meals on a budget
- Plan meals around what is safe and rotate a few reliable favourites.
- Batch cook allergy-safe meals and freeze portions.
- Keep a list of approved products and brands, and recheck labels regularly.
- Prepare for schools and outings by packing your own food when you cannot confirm what is in it.
A note about price comparison
ShoppedOut compares prices, but it cannot tell you whether a product is safe for a particular allergy. Always read the label on the package you are buying.
The bottom line
Careful label reading, a few kitchen habits, and advice from your health care team make allergy-friendly cooking manageable. Budget tools can help with cost, but safety always comes from the label and your own checks.
