Just "wanting " to move to any part of Canada, is NOT enough.
BOTH of your Parents MUST apply and qualify as Immigrants, before they can move to Canada.
Their applications will be approved. or not, based on their formal educational levels, and their past employment history. Canada is looking for people who have a University degree, or who are a certified trades persons, such as a automotive mechanic, welder, carpenter , of the like.
It is a competition, and only the best are selected. The application process takes at least two years, to be completed, so don't pack your bags yet.
And finally, black people in Vancouver are a very small minority, less than one percent of the population of that city, and many of them are from Africa, or the Caribbean, not the USA.
