TLDRHealth Canada has introduced new rules to double the amount of vitamin D in certain foods like milk and margarine to ensure Canadians, especially teens, get enough of this essential nutrient.

As sunlight is less available in Canada during winter, these new regulations aim to help people maintain adequate vitamin D levels.
