Things that occur to me while reading newspaper letter sections

Has there ever been a war in which Canadian troops were fighting for anything even vaguely resembling Canadian citizens' right to vote? Because you can be damned sure that this argument - that not voting dishonours the memory of our fallen soldiers who fought for our democratic rights - will get trotted out any time voter turnout does. Canadians have fought some just wars - World War II was an eminently just war fought for a mixture of just and unjust reasons, and I happen to cautiously file Afghanistan under the "just" heading as well - and some unjust ones, but were there any in which our right to vote was even indirectly threatened? Hell, you can make the argument that the War of 1812 was essentially a war in which Canadians fought against the right to vote, though I don't suppose that was a primary motivator.
