Canadian with Right of abode -fiancee canadian

My fiancee and myself are canadian. both with canadian passports and i have my right of abode.

i've been reading in here and i'm gettting confused.

The uk is ultimately where we want to be.

does anyone know what kind of visa's we could apply for him to get him over here legally?

and also - if we were married would there be another way to go about it>?

thanks for your help
