On a brighter note, YVR has just become the first Canadian airport to offer a "Doggie WC" facility for those travelling with pets. I believe it's inside security in the U.S. departures area. Here's the story.....

Nicole,
It's likely the larger airports (Toronto, Vancouver, Montreal) may be more affected with the lack of screening staff than smaller airports, as they process a lot more passengers. At the present time, Halifax is the eighth busiest airport in terms of passenger traffic, while my home airport (Kelowna) is 11th. I've found that certain times of the day can be busy but for the most part, the process seems to move along reasonably well.
Tom,
Hopefully those in charge will deal with problems before they become too serious. The last time I transited through Toronto about a year ago it was a miserable travel experience for several reasons, but I got a first hand look at the lack of screening staff. The security checkpoint was processing a large number of passengers from the flight I was on from Paris using only two agents. When I finally got to the end of the line, I asked the screener why they didn't have more people working for such a large volume of passengers. His answer was, "they've been laying-off staff lately". My reply was "what kind of an idiot would lay-off staff in the middle of peak tourist season". He just shrugged his shoulders. That wasn't the end of the problems, but I'll leave it at that. Hopefully YYZ gets their problems sorted. I'll be through there again in a couple of months, so we'll see?
