Can anyone confirm from experience that YTZ (Billy Bishop) is not included in the random testing system? I know most of the articles say the four major airports, but the government's press release only mentions Toronto, which suggests that YTZ is included with YYZ.
I'm looking to head from Chicago to Toronto in November, and flights from MDW to YTZ are about the same price as flights from ORD to YYZ. If I can avoid the chance of random testing, seems like YTZ makes more sense?
