How is this regulated in Canada?

The Canadian Food Inspection Agency said in an email that it is responsible for the surveillance of chemical residues in foods and how they follow Canadian regulations, while Health Canada sets the maximum level for environmental and industrial pollutants in food.

However, it’s not clear whether these protein products are regulated as food or natural health products, and Health Canada could not respond to CBC’s questions by deadline.

Goodridge wants to see Health Canada set guidelines for these protein powders or dietary supplements, he said.

"There are no specific federal limits for lead in protein powders or dietary supplements," Goodridge said. "This, in my opinion, is a big regulatory gap."
