I want to sell 50% of a duplex I own to my Dad. Is this possible?

[Mitchell P.]

I own a duplex that has significantly increased in value over the last two years. I would like to extract some of that increased value so that I can purchase another property. I'm looking at selling half of the ownership of the home to my Dad. Is this hard to do? Will my mortgage company give me a hard time?

I live in Canada.
