I've had very similar experiences, and this coming from somebody who travels on a Canadian passport. My interactions with Canada immigration are often more convoluted and more questioning than US immigration. I also think the US preclearance guys that work in Canada are some of the friendliest in the system (maybe side effect of living in Canada?)
