Importing could be a challenge
The regulations for Canada make it very difficult to import a bike that is not made for sale in either Canada or the U.S. Here is the quote from Transport Canada:
VEHICLES PURCHASED OUTSIDE CANADA AND THE UNITED STATES
The Motor Vehicle Safety Act
and Regulations require that all vehicles imported into Canada comply, at the time of importation, with the Canada Motor Vehicle Safety Standards in effect on the date the vehicle was manufactured. Vehicles manufactured for sale in countries other than Canada and the United States do not comply with the requirements of the Canada Motor Vehicle Safety Act, CANNOT
be altered to comply and CANNOT
be imported into Canada. The only exceptions to this rule are vehicles fifteen (15) years old or older
as determined by the month and year in which the vehicle was manufactured and buses manufactured before January 1, 1971.
Hopefully you were just looking to bring your bike in to ride and then take it home. If that's the case it is very simple with either shipping (as per previous post) or fly it over.
