Hi Tommy, and welcome!

In my experience, transition is very much a personal thing. It's entirely about getting yourself to a position where you can feel comfortable with yourself. For some people, that could mean things like changing your presentation: cutting your hair, binding, packing etc. but not going through a medical transition. That's fine, and it is much more successful if (as others have said) you are already reasonably masculine in your presentation. But for others (such as myself), nothing but a full medical transition will do.
I tried all the social stuff like changing my name, my presentation, getting new ID identifying me as male etc. but
nothing stopped the 'madams' and the 'loves' and the 'shes'. The only time these things stopped for me was after I'd been on T for about 8 months, when my face shape started changing, my voice was significantly lower, and I had sufficient facial hair to not be identified by other people as a 'butch lesbian' - which in my case couldn't be further from the truth, because I'm not into girls and I never have been. Maybe I was just unlucky? I know other guys who have been much more successful. But for me, it had to be T and top surgery at a minimum.
So my advice to you would be to try all the social stuff first and see if it's enough. If it works (and it could well do), great! But if it isn't, then you know you still have the medical route to consider.
There is one other thing though: you mentioned...

perhaps even going as far as seducing a straight chick that didn't freak when she knew you were transgender?
That right there is a huge can of worms and you'll need to think very carefully about how you approach this.
I'm not sure about the legality of this in Canada, but in plenty of countries there have been court cases where people have been prosecuted and convicted of sexual assault for not telling partners that their biology doesn't match their presentation. It's very controversial (and you'll see a bunch of opinions here on all sides) but the gist of it is that everyone has the right to consent to sex with whomever they fancy, but that consent can be called into question when a person specifically consented to have sex with a man, but that person turned out to be legally and physically female (or vice versa). This is hugely discriminatory because the same doesn't apply if somebody doesn't disclose, say, their true age or their marital status or even their STD status, but that is the way the cookie crumbles in many regions so you need to do your homework & tread carefully.
It's for this very reason (and others) that many of us think it's safest to come out to any potential sexual partner before any sexual activity commences. That way, consent has been properly established and everyone can (hopefully) have a good time. So charm her with your awesome self, go out on a date or two, and then disclose your status. If she still wants to go for it, you're on to a winner. If not, she probably wouldn't have been OK with it anyway and most importantly, she probably wouldn't have consented. It sucks to have to do this, but in many cases we don't have much choice, particularly if you don't undergo any medical transition.
As for how you go about 'seducing a straight chick'? Not my area I'm afraid.
