With regard to the food service industry and the area we focus on, the regulations require that one person per shift be certified as a food handler. The idea is that, in most jurisdictions, you'll be required to have at least one person present during the preparation and service of food who has some education and knowledge about food safety in the operations. That's currently the standard across Canada, as far as it goes.
The way they get their certification is quite diverse. There are a lot of private sector organizations, such as ourselves, that develop and deliver training and certification, as long as that certification has been approved or recognized by all of the different jurisdictions across Canada that require it.
