More than half the money visibly donated to the anti-vax roadblocks in Canada came from Americans. A little over 1/3 came from Canadians.

In effect, these money-transfer sites have become a system for destabilizing Canada. It would be wise to prevent their use for this purpose.

I suspect that American right-wing billionaires are providing money secretly to be used to pay their parking tickets.

If the protesters are being supportes by rich foreigners, it enables right-wing protesters to disregard fines the way megacorporations do. In both cases, this calls for increasing fines until they are too much to ignore.
