What is the cost to repair a screen for iPhone 10XR?

I bought 3 new I phones end of May I think and with two of them with protective cases and a screen protector we're purchased at a Telus Store, the one screen not too bad but the other one it's pretty bad. I've been with Telus for years and I always purchase new phones every two years and have never had screens break like these ones have. What is cost to repair screen for iPhone 10XR? I live in Alberta, Canada. My cell number is 780-***-****,
