Ok i am in debt and would like to buy some land and build a house what is the best way to do that?

I want to buy my father-in-law's land from him and build a house for my family(he will be living with us) what is the best way to get financing to do that? I live in Canada if that helps. Would I be able to get a mortgage or would that fall under a line of credit or something completely different? I don't have anything for collateral and may have a co-signer if need be. Any and all help and ideas are welcome. Don't forget I live in a small town Nova Scotia Canada. thank you in advance
