Minimum down payment on a house in Alberta?

[gilleabart]

So I want to be a home owner and not a renter but theres always the fact the down payment can be difficult to come up with. I was wondering what the laws are on the down payment cause when I look online I find so many different things you don't know what to believe. I've heard you don't even have to put a down payment on your interest rate may be higher. Also I've heard you need at least 3.5% or 10%. If you people would be able to help me clear this up it would be great. Thanks!
