Transferring from California community college to lifesci at Waterloo

Hi I’m planning on going back home because my status here for green card is taking longer than expected and frankly I’m not willing to go into piles of debt just to get the same degree I would in Canada. However, I want to know the opinion of you guys if this is a good idea because I’m a pre med student. I am going to attend Irvine valley college and hope to transfer by the end of next summer if possible to Canada. Is there any downside that I should take consideration into and if it’s even worth it at that point?

Additionally I am a Canadian citizen
