Ken__W, are you suggesting that your sole expertise on matters of gender is that you consulted a dictionary? Or do you have some other expertise?
Actually, if you read the Charter, although it says everyone is equal before and under the law,  you will notice that it specifically defines categories that cannot be discriminated against. 
"15. (1) Every individual is equal before and under the law and has the right to the equal protection and equal benefit of the law without discrimination and, in particular, without discrimination based on race, national or ethnic origin, colour, religion, sex, age or mental or physical disability."
Note that transgender people are not mentioned, which some people might interpret as a license to discriminate against them. 
My question to you is why would it make a difference in your life if transgender people are added to those in the above list? 
(No, I'm not trans.)
