Entering the industry as an international film student

I’m an American looking to get a student visa and study film editing/production (aiming for Sheridan College or York University) in Toronto. Essentially, I’m trying to gauge how likely it is to get hired once I graduate, before dropping $100,000+ on school lol

I’ve heard that Canada has some policies around how films/media are produced and funded, like how a certain amount of the cast has to be Canadian. Are there any policies that might make it more difficult to enter the film industry as an international student? How difficult might it be to find a company that would be willing to sponsor me once I graduate?

Thanks!
