Replying to Broken Camera

I got a samsung sport cam in the summer and used it quite a bit. Now after ive only had it for about half a year the mic is fucked and just the other day I was filmin a picnic table jib setup and the screen stopped working. Since the camera doesn't have a normal viewfinder i'm kinda fucked. If I take it in to get warrantied (from London Drugs) will they be able to replace it? If not, is it possible to get it fixed somewhere? Thanks.
