Running copper piping along the outside wall of my house

Hi all. New to this forum, but an avid DIYer. I have a question that maybe someone here can help me with. I am in Montreal, Quebec, Canada and i am building an extension to my deck. This will then cover up the water faucet that is outside my house. Right now it goes right out the wall and stops there. I was wondering if i could remove the faucet, extend the piping along the wall, re-attach the faucet and anchor that to the wall. In theory it sounds all well and good but i want to make sure i am not breaking any code or anything like that. It gets frigid cold here, but i shut off the water in the winter from the inside and leave the outside faucet open to make sure they don't burst.

Thanks,

You should be fine as long as you have a warm shutoff and the outside line can be drained for the Winter.
