I'm buying my house in BC with my fathers funds from Europe. How will this lump sum be considered and taxed? Should a take it as gift or loan? Or does it matter at all?

The money is used to buy a private property in which I'm going to live, I don't have a mortage. 

I guess the options are to either lend it from my dad as a low interest loan or quite simply take it as a gift to buy the house.
