Just a post-script to what Mike C. has already written above:
Canada follows pretty much the same protocols as Australia, although probably not quite as strictly because Canada is not an island.
What the Canadian agricultural people want you to do when you bring a vehicle in from another continent is to make sure that there is no soil on it anywhere, and no bug guts on it anywhere.
So, this means all you have to do is a really good pressure wash, followed up by a really good hand wash (to get rid of any leftover dust or bug guts), but, instead of focusing your attention on making sure that the parts everyone sees are clean (like the tank, the seat, the sides of the engine), you want to focus your attention on making sure that the parts that no-one (even you) ever look at are clean.
This means underneath both the front and rear wheel fenders, way up at the top of the front fork shocks where the bug guts go after the bug explodes lower down on your front forks, underneath the bottom of the engine, underneath the bottom of the center stand and side stand, and in between the treads of the tires.
Plan on spending about $5 at a local coin-op car wash, and then about half an hour with a bucket and a brush. Then give the bike one final rinse. When the agricultural folks see that you have obviously made a serious effort to make sure there is no soil or bug guts on the bike, they will appreciate your efforts and let you through.
