If he already living and working in Canada?
If yes, then after you're married he can sponsor you for PR. It will take about a year, and he will have to stay in Canada while that happens - he can visit you for a couple of weeks, but he can't stay outside Canada for too long.
If you have a tourist visa to Canada, you will be able to go visit him. If not, it will be hard to get a visa while your sponsorship is being processed.
You should both make plans to live apart for some time while all the paperwork gets done.
If he is not currently living in Canada, he will have to move to Canada first before he can sponsor you. Alternatively, you can apply for Express Entry (if you qualify on your own).
