Where should I start

Hello, I am a US citizen and absoutely love Toronto. I met the man of my dreams there and I would like to eventually live there. I dont know if I would live there permanently yet. But for now I have my BS in Communications and plan earning my Masters Degree. My question is where do I start? I would like to be able to live and work there and if things work out go to college in Toronto. So what do I apply for? My boyfriend unfortunately is unable to enter the US because he has some things pending on his criminal record. I know I could stay and live with him. I plan to move there in October which is why I need advice on how to go about it. I do have an extensive work background,clean record,good health,and college degree.
