I've heard similar accounts, and anecdotally holds up, although my experience travelling for work specifically is limited. Incidentally, as a Canadian, I've been searched many more times, if not 100% of the time, coming back from the states than going in. Security theater in both directions though for sure, just looking for a slip up. Going in to the states, I once had a slightly vague answer about where I was staying because I'd planned to camp on a long road trip. They pulled me into the lineup and then asked me again, I tried explaining but they just wanted an address and hinted as such, so I just google searched a hotel in front of them and gave them that. They've got boxes to check.
