Hi and welcome to the forum.

Basically, it looks like you need a job offer or a job qualification that is in demand in Canada. I don't know the chain Tim Horton's but there's no reason you couldn't ask about moving to one of their stores in Hamilton - or to their headquarters (wherever that might be). Worst they can say to you is "no."

Another option might be to move up there on a student visa and finish off your college work or apply to a training program for something on the list of "skilled professions" that are eligible for a work visa. From there you can apply for a work visa when you've finished your studies. (Obviously, that takes having some savings to live on.)

Canada doesn't have a fiancé visa, but once you're married, your spouse can apply to sponsor you, provided he has a job adequate to support you for a bit.
Cheers,
Bev
