What is the best savings account to save for a house?

I'm almost 20 and want to start thinking of my future. I'd like to open a savings account to start saving for my own house but I've never had a savings account before and don't know anything about them. I want an account that is pretty well on lockdown that I won't be able to take any money out of. I was just wondering what banks in Ontario have the best savings accounts to save for a house.|||No bank they are paying less then .5 percent. Open a money market account and mutual fund account.
