New immigrants apply to Canadian universities. Do they need to provide China's high school grades?

High school grades and above are generally required. High school grades are generally A and B, and there are many majors in universities. For adult students, they only need to take specific exams. If it is a major with a bachelor's degree, domestic high school scores are not enough, and local high school scores are also needed (for example, English 4U is a must). There are two kinds of level authentication, one is WES (the other is forgetting). WES's partner is a domestic degree certification center. Is it accredited by Tsinghua?
