Hey Kazzy, I'm doing the same thing as you are. We don't have anything big, so we're just sending stuff through mail as we box it up. Nothing has reached Canada yet, so I don't have any updated info for you, but I have shipped boxes and even a full suitcase before and they came through alright. It's also reasonably priced as well. Sent 2 very large 18kg boxes last week for $100 total.
On another note, I have a question about address changes. They received our package in Mississauga on July 10 and we are waiting for my sponsorship approval. However, we need to move out of our apartment on August 15 and won't have a permanent address again until we hit Canada on sept 10 where we will be staying with my parents. How do I change our address at this point in time since we're not in Canada yet, and we don't have any account numbers or anything because I haven't been approved yet. Do they send any paperwork out during or after the approval process for sponsorship or is that only through email? (I did fill out the email part on the app)
Thanks
Ct
