I guess everything is relative... I always find Canadian law enforcement a polite, refreshing breath of fresh air after (or before) dealing with US Customs and Border Protection. It's like a whole other world up there. I'd tell you to be grateful but if all that paranoid, wannabe tough-guy stuff is drifting north and infecting the RCMP and CBSA, I can only apologize and sympathize.
The silly thing is that all the attitude and aggression not only annoys people, but also makes a mockery of the actual security at the border. We got our usual chilly reception coming back from Canada last summer through the San Juans and when it was done, all I could think was, "What do you have to act so tough about? You couldn't even find the case of whisky in the quarter-berth!" It's more sad than intimidating... a lot of puffery from a few people who are pretty incompetent. I think it probably encourages, rather than deters, our real enemies, and just ticks off our friends and fellow citizens.
