Hi Rockwell:
I've shipped my bike back and forth between Canada and Europe numerous times. I've always shipped it by air, using
Motorcycle Express to organize things for me. Their rates vary a bit depending on the point of origin and the destination. I usually ship Paris to Toronto (and vice-versa) because that is significantly less expensive than shipping out of the UK.
If you ship by air, the bike doesn't need to be crated. Just show up with less than 1/4 of a tank of fuel in it. No need to disconnect the batteries, etc. You just ride up to the freight terminal, the price of the container, pallet the bike is strapped to, etc. is all included in the price.
You might want to check out the cost of shipping by air before you go further along the 'crating' path. I suspect it would cost you about $2,000 CAD to ship one way Europe to Canada.
As for the ISPM-15 requirement for your wooden crate, I have no idea how you will be able to comply with that, unless you can find a lumber yard nearby that stocks wood marked with that certification standard.
Finally, a couple of lessons from the "school of hard knocks" that I learned long ago, first time I shipped my Canadian bike back to Canada:
1) Make sure the bike is clean enough that you could eat off of any part of it. In particular, make sure that there are no insect remains or dirt particle remains anywhere on the bike, including under the fenders, etc. Otherwise, Agriculture Canada may require that you get it steam cleaned before releasing it from customs.
2) Make photocopies of the Canadian registration (plate portion of the Ontario vehicle permit) and, if you have it, your original bill of sale from Canada. Attach these to the paperwork for the shipment. Attach similar copies to the seat of the bike itself (or outside of the container, if you crate it). This will help make clear to Canada Customs that the bike is "Canadian Goods Returning" and not a foreign vehicle that is being imported for the first time.
Be darn sure you have the original of the plate portion of your Ontario plate permit with you when you go to pick the bike up. Doesn't matter (for customs purposes) if the plate is current or not.
