Is children's education free in Canada? 

In Canada, primary and secondary education is generally free for Canadian citizens and permanent residents. However, there may be some costs associated with certain educational programs, such as optional school trips or specialised courses.

In addition, there may be fees for certain services or supplies, such as textbooks, transportation, or extracurricular activities. These fees can vary depending on the province or territory and the specific school district.

It's also worth noting that post-secondary education in Canada is not free, although there are a variety of financial aid programs and scholarships available to help offset the cost.
