For those of you who may not know, it is much easier for a Government to amend a Regulation than an actual Act, and this is what Stephen Harper's Government has done. Pure bigotry and hatred against the Trans community here.
For those of you affected, i urge you to file complaints with the Federal Human Rights Commission upon refusal to board.
