I received one of the ID reminder cards early this week.

I don't think it's just a borrowing from down South -- it's a bit more nuanced than that and is more related to veiled voters in Quebec.

For most people, it just involves showing your driver's license. For those w/o driver's licenses, or students, it's more of a nuisance, but Elections Canada has, to their credit, offered a LOT of options to prove your identity & residency.

It's amusing, though, that a passport is NOT enough on its own...
