If you search around on the Forums you will find various threads about international air travel with guinea pigs.
However, the rules and regulations change on a regular basis, so you would need to keep up with those.
It has also become increasingly more difficult to find airlines that allow piggies in the cabin, which means the best (and often only) option may be to use a pet transport company.
This will be costly and can have a lot of drawbacks, plus you need to seriously consider the climate at the time of year you will be travelling.
It is certainly possible and can be done, but would require a lot of time to look into the rules related to the specific places you want to fly to and from. My first step would be to try and find an airline that will consider allowing piggies in the cabin. Also looking at the Canadian government department for animal imports to check their current rules.
