My first question is are you sure that you want to send your bike over? If you have a low cost bike like an old Transalp, it'll cost you more to ship it there and back than you can buy one in Canada or the US.
If you want to get an idea of prices to compare shippng to buying, check out craigslist.com for used prices, the US is cheaper than Canada to buy bikes.
Also, with a local bike it'll be straightforward to insure. At the end of your trip, you can easily just sell the bike, which is not possible if you bring in a foreign bike.
