Here is a link to my answer to a previous post.
Since you are in California (and if you are not planning U-Haul, or U-Pack), then there is another option I almost committed to. I know a mover friend of mine based in San Diego, and he can move your stuff upto the US border. From there, you could either U-haul or get a Canadian mover to ship. It does need some coordination, and was a little bit overwhelming for me with 2 kids. So we opted out of it. If you wish to explore this, let me know and I can connect you to my friend.
