Once you have started dating online in Canada, be proactive!
The best way to know whether a single who attracts you is date worthy is to chat with them!
Trans women who were attracted to women prior to transition, are still into women post transition.
Even opposites can attract (no magnetism needed here, just chemistry).
Make your dating choice from among the singles you fall for – it’s much better than being matched with someone artificially by some pseudo-intelligent system!
Cis is the exact opposite of trans, and is used to promote equality between cis and trans folks (when using "women" and "trans women", some people feel that the comparison devalues trans women or makes them lesser than cis women).
Interestingly, trans people who were "straight before" generally continue to still be attracted to the gender they were originally attracted to.
Choose one where you look natural, the one showing the real you.
