Canadian law is likely different than US. But you did surrender it to him voluntarily, and the most you'll get is community service if you plead guilty. I'd find out if the community service/etc will be on your record in that case.

Just to analyze a bit, what happens if you plead not guilty? The cop will have his evidence, maybe even video, that you got pulled over and surrendered marijane from your own pocket to him. How can you beat that?
