Canada is changing its risk assessment policy for genetically modified plants and food products sold at home and overseas. Genetically modified organisms (GMOs) that contain foreign DNA will still be subject to government regulatory oversight. However, a new category of GMOs — gene-edited organisms that do not contain foreign DNA — will be exempt from safety assessments by Health Canada and the Canadian Food Inspection Agency (CFIA). To date, these are mostly crops like corn that have been modified to enhance a specific, naturally occurring characteristic, such as high corn starch content.

Gene-editing techniques are also common in medicine, including in vaccines like the AstraZeneca COVID-19 inoculation.
