Same international far-right nexus?
I don't think any of us west of the pond know anything about the BNP or any of the other groups you mention. We see brief news mentions, but no context or anything to attract our interest, so your suggestions are nonsensical.

There are some small bigoted groups in both U. S. and Canada, but nothing cohesive or national. The shooting at the holocaust museum brought one of these people to light, but nothing like what you seem to be looking for.
