Of course, you need 19-year-old adults in BC Province. You were under 18 when you entered school, so you can't bargain with the embassy. You can find a Canadian resident or an adult with a maple leaf card as your guardian, preferably from BC province, because Canada is more serious, and they will ask this guardian to perform his guardianship duties. If it is from other provinces, they will think it is unqualified. If there is no suitable candidate among your relatives and friends, contact the school admissions office and write an email stating that you can't find a suitable guardian. I hope the school can help solve it. After receiving the letter, the school will appoint a school staff member as your guardian and send you a guardian's note. You can have this notarized. When you apply for a card, your parents should go at the same time, and bring the guardian form downloaded from the Canadian Embassy in China or visa center, as well as your household registration book, ID card and birth certificate, to prove that your guardian in China agrees with the guardian designated by the school. That's enough.
