Wish I could think of or find more websites. Tryouts have already began at some clubs and will soon begin at others.
Not ready to play club then check with your local community sports association and play spring basketball in the CMBA.
Think you are too old? Wrong. Mount Royal University has there popular spring Ranger Elite League. Sign up and they will place you on a team. Ex-high school, ex-college, ex-university. There is a place for all levels. There is also very active woman's and men's leagues for fall and winter.
I know I've missed some clubs. Please offer your information the above list.
