Security at YYZ
 

How come a small airport like YHZ can have upto date security equipment where you don’t have to take anything out of your bags while YYZ is still the old fashioned way? The security was rude too.

That wasn't my experience. Just went throuth YYZ security yesterday on my way to LHR. Didn't have to take anything out of my bags and the security staff was neither rude nor overly effusive. They just seemed like they were getting on with their jobs to me.
Guess it's another example of YMMV.
