GA around Vancouver

I currently fly just outside London where my club has ~10 planes to hire. I'm considering moving in the general Vancouver (BC Canada) area and wondering what GA is like?

I did some research and found a club where 19 people share one plane...with a $2k initiation fee...is that normal?

Is there a flying club where I could just rent a Cessna or PA28 relatively easily? (Without being a shared owner)

Also, sea planes are cool. Is flying a sea plane achievable for a PPL? By achievable, I mean accessible and not insanely expensive for a hobby.
