Just learned from a city inspector that Edmonton's frost line depth is 1.8 meters, which is way deeper than I thought.

Found this out when I was planning a deck footing and it completely changed my material list and digging schedule, so has anyone else had to adjust a project for our local ground freeze?

My neighbor's fence posts started leaning after one winter because he only went down a meter. That frost heave is no joke around here, it basically acts like a slow jackhammer. Definitely worth renting a power auger for that depth.

Yeah, I had to go that deep for a shed base last fall. Rented a two-man auger and it was still a full day of hard work. Saved me from a cracked foundation come spring though.
