Health Canada received novel food notifications for 3 canola protein isolate ingredients that are made from the seed meal that is left over after oil has been extracted from canola seeds.

You can find information about the canola protein isolate ingredients and Health Canada's safety assessment of them here:

For information about canola oil or rapeseed oil and mustard allergy, please see "Do I need to avoid canola if I have a mustard allergy" and "Do I need to avoid rapeseed oil if I have a mustard allergy" in Mustard: A priority food allergen.

Canadian labelling requirements

Health Canada expects food manufacturers to label all foods that contain a canola protein ingredient, but do not contain mustard, with a cautionary statement indicating canola protein may not be suitable for individuals with mustard allergy. This allows people with mustard allergy to make an informed food choice.

Canola protein isolate can be derived from several different species including:

If the canola protein ingredient is made from canola-quality mustard, the food must be labelled according to enhanced allergen labelling requirements because mustard seeds is a priority allergen.

If the canola protein ingredient is made from a rapeseed species of canola, the food must be labelled according to usual labelling requirements for food ingredients.

If you or your family member has a mustard allergy:

If you aren't sure if a pre-packaged food contains canola protein, contact the company named on the label.
