Not ALL Canadinas are bad!
I have to say that I love Toronto, and Canadians in general. I am always impressed by their friendliness and their genuine fondness for us Yanks.
To respond to your question about security at Toronto's airport, I can only speak to their International Airport.
Security there is every bit as good (or bad, depending upon your viewpoint) as that at DCA or IAD. It is no where near as good as it is at Ben Gurion Airport in Tel Aviv or at Gatwick or Heathrow in London.
Passengers flying from Toronto to the USA clear American customs before they board their flights to the USA.
It would seem to me that if there is any lapse in security on flights coming into the USA from Toronto, our American customs agents would bear some responsibility.
Also, you may want to get better informed about a places background when making broad comments. Saying MOST of Canada is of French descent is plain incorrect, especially when talking about Toronto and 95% of Ontario.
Security wise I can only go by my own experience. Flying out of San Francisco, Dallas and Phoenix recently, my laptop, digital camera, etc wasn't even checked, yet every time I have flown out of Toronto, every single electronic device in my carry-on has been checked. Also, every single person flying from Toronto in the U.S must go through U.S. customs, which in theory should improve security.
As for security, I flew through Toronto, Calgary, Vancouver, Montreal and Vancouver over the past 3 months and honestly, I was pleasantly impressed with the way airport security is being handled. It appears they've put extra people in the screening areas and supervision is much better than it was pre-9/11. I didn't take any longer to go through security than before but the checks were much more intense. All carry on baggage was opened, and I mean everyone's. All electronic gear had to be turned on, not just inspected. Generally very courteous screeners, too. What I didn't see any evidence of was some of the wierdness many folks here have described happening in some U.S. airports...confiscating toys, being really anal with elderly people who are about as far from the profile of a terrorist you could imagine, humiliating passengers, that sort of thing. Just very thorough and generally polite inspections with extra room to turn on laptops, check bags etc.
I was expecting much worse, and as I hadn't flown since 9/11 I was relying on horror stories as perception. Frankly, I've never felt more confident than I did with the inspection routines I saw, and it was consistant at all the 4 airports.
If there was any idiotic behavior going on I didn't see it.
