What are you looking to climb (sport? trad? top rope? gym?)? What days are you looking for partners? What kind of experience do you have? Do you have a car, or will you need to car pool?
Lots of people and lots of climbing in an around Hamilton. You should be able to find someone if you spend some time climbing at Gravity in Hamilton or Climber's Rock in Burlington. If that fails, just head out to Rattlesnake or Nemo and try to join some people climbing there.
