Student loans for medical School

Okay so heres my situation. I currently live in Canada but I have UK citizenship. I was hoping to go to Uk medical school, but turns out unless I have lived in the Uk for the past 3 years I have to pay international fees.

I'm lucky enough to have been working and saving (20K) , plus having some generous family contribution (80K) I would need to take out a loan to cover the remainder.

I'm looking at getting a PSLOC of up to 350K to help pay everything, then I would pay the interest as it comes up.

I'm still in the process of looking everything up and figuring this all out, so i'm very new to this and confused. Does anyone have any advice or has gone through a similar path?
