Climbing near Vancouver (CAD) and North Americe

Hi I'll go to Vancouver in Canada on 1st August. On 29th August will start my exchange student trimester. In the time between I want to do some climbing. I know that in the near are some great spots. 1. Are there some special websites or spots in Vancouver where I can easily find a climbing partner? Should I take a Rope with me? 2. My trimester will end in decembre and I'll have January and February to make a trip and climb. Do you know good climbing spots in Westamerica (Canada or USA) which are climbable in January and February?
