VIATeC has a job board [1], which I have personally used to find several jobs over the last 10+ years, so it works. I would look for something similar in your community and hope they have an equivalent. craigslist.ca is good too.
If you want to look at the province as a whole, there is the BC Technology Industry Association, and they also have a job board [2], with 1116 posting no less!
