Usually those prices only can be provided by the store, as long as you're sure that there is no Watter Damage at all, they can fix it for you.
If you dont want to go to the store and want to know price first you can go here: http://www.telus.com/forms/stores/en/find-a-store.jsp?cmp=mobility . Then enter your Postal Code and find closest store to you, you might get phone number so, you can call them just to have an idea.
I hope you will find this information helpful! 🙂
