I recently traveled through YYZ Terminal 1 heading transatlantic and observed a CATSA agent conducting random swabs of passengers in the security line, prior to the actual screening. No big deal, except that he was ONLY pulling out men! I observed him for a good 15 minutes and counted twenty men and zero women pulled aside for "random screening". How random is it if 50% of the population is left out? Is it not unconstitutional?
