Help: iphone 5 got hundreds of dead pixels!

Did you try going into an Apple store (it's not 100% clear from your post)?

Is your phone factory unlocked purchased from Apple?

I've heard that some people have been able to get a warranty replacement in another country but then others have said the warranty is only valid in the country where it was purchased.

 

If you have Apple Care you might could go in a store for replacement ... But not sure what happen to the SIM registration once your device changed. Any plan to go back to home country for holiday season ? Or possible to send It back and ask someone to change in Canada and rent a phone to bridge the time

 

If there is an Apple store near you, just go in and give it a try. I've definitely heard of people replacing their defective iphone abroad.

 

Woah, did the screen just start doing that or did something happen to the phone? Just making sure because if something happened to it, then the store probably won't help you out anyway.

 

That's crazy! I've never seen a screen with so many dead pixels. # Sorry to hear about that. I would definitely do what the others have said. Just try to take it to a store and see if you get lucky outside Canada.

 

Whoa, yeah go to the nearest Apple store and show them what your phone just did and ask if they can help you with it..

 

As long as you didn't damage it Apple should take care of that free of charge I would imagine. The picture its kind of hard to tell, but it looks crazy.
