Hanno pretty much has it, not sure of the exact size, but ...
The real difference is that the US wheels / tyres have a 5 degree angle on the seat, wheras British / Canadian ones don't.
It is quite easy to fit British tyres on US rims ( I've never heard of problems doing this, despite the size difference) but doing it the other way round wouldn't be easy as you have found out.
Given the choice of;
1. Altering the rims to suit the tyres (hard)
2. Altering the tyres to suit the rims (easier, but how safe?)
3. Forcing them on with a damn great press.
I think number 3 would be my choice, with plenty of lubrication and cleaning, maybe a hair of grind back on the tyre seats.

It all boils down to the fact that the bead diameter of the British/Canadian 16" tyres and rims are ¼" larger than those of US 16" tires and rims.
