I live in Toronto, but I also live very close to Markham. It can be recreational or competitive, and I'm 13, so it has to be eligible for juniors, too. Thanks if you answer
YMCA in MARKHAM at Kennedy and HWY 404 Some players at YMCA are EXTREMELY GOOD Also try Mandarin, or Everyday Badminton (LOW CEILING) Players are also EXTREMELY GOOD
In Scarberia there's Agincourt badminton centre near birchmount and ellesmere. Up in Markham other than the ones mentioned above there's also Suria Badminton. But if you're lookin for a club there are about a hundred billion million. Ok maybe slightly fewer than that but quite a few. Check out Ontario Badminton Association. Then click the "Where to Play" link. You'll see a whole bunch of registered clubs, many which are home to all levels of players. Good luck to you. Maybe I'll SMASH into you sometime on the court.
