Be Allergy-Aware

  • Read ingredient labels every time you buy or eat a product.
  • Do The Triple Check and read the label:
    • Once at the store before buying it.
    • Once when you get home and put it away.
    • Again before you serve or eat the product.
  • Always carry your epinephrine auto-injector.
  • For tips on eating out, visit our guide for dining out with food allergies.
  • Check with manufacturers directly to see if the product is safe for you even if your allergen is not listed on the ingredient list.
  • Be careful when buying products from outside of Canada, since labelling rules differ from country to country and the term “spice” may include mustard.
