For rubber boots, Baffin makes good industrial boots. We have quite a few of their various models for different things and they've all been good.

For leather boots, I just wear Blundstones. I like the winter model or the all-terrains since they have a better sole. They are not quite BIFL-rated but I do get a good three years out of them farming and logging. Better would be CanadaWest, made in Manitoba, but they don't make my size. (The men's sizes don't go small enough and the women's don't go wide enough - if you have dude sized feet you'll likely be fine)
