Sec 5.2(1)(c) of the ID screening regs of Aeronautics Act: “An air carrier shall not transport a passenger if the passenger does not appear to be of the gender indicated on the identification he or she presents.”
Canada, you’re disappointing me. Additionally, I think it is of note that this has way more to do with passing privilege than pre/non-op (though for some people that does make passing as cis more frequent), though another example of this going poorly I can think of is someone on hormones who doesn’t have their identification changed. I don’t know why it can’t just be, if you in general look like your picture on your ID (or have some paperwork explaining why you don’t).
