Hi there Mitchell and welcome to CC. Your story touches me - I have a 17 yr old son and I'd hate to think of him facing such difficulties so young.
Ron has given you some good advice - especially about taking time to think things through. My first concern is that you seem to feel your safety is in jeopardy. For now, until you figure out what you're going to do and how you're going to do it, please browse through this link
and this one
. Yes, they are government programs, but please don't let that deter you from accessing the help that is there for you. You don't have to do this on your own, nor should you have to.
I'm hoping there may be some resources in there for you to keep you safe so you can calmly consider your next step.
As for your car - older cars from Ontario can be very difficult to sell in other provinces - it will require a safety inspection, which may be difficult to pass - particularly if there's any rust on it. If you think you'll need the money from selling it, I would recommend you do that in Ontario.
Also, if you're planning on moving to Alberta please please do some research first. Rents here are beyond ridiculous. A one bedroom right now goes for about $900-1,400 per month. As to what MacDonald's is paying, it won't come close to paying your rent, utils, food, ins. etc. and I'm sorry to say that living in your car just isn't an option in Alberta. It's far too cold here to consider that.
If you don't mind me asking, is getting a higher education on your 'to do' list? I believe there are tons of resources available to help you achieve this, no matter which province you land in.
Again, I'd really encourage you to rethink your stance on accessing help. Those programs are there for people like you who need them... making good use of them so you can live decently and hopefully go on to make a productive contribution to society is exactly what they're intended for.
Also Mitchell, at some point I hope you consider obtaining some counseling to help you deal with the abuse you've lived with. The scars on the inside last much longer than the ones on the outside.
I'm sorry to hear of your troubles, I hope you find a safe place to land very soon.
