Help!Quick!Does Tim Horton's Drug test?

I have an interview in a few days and I've already failed one test for a different company so I can't afford another. I know Tim Hortons is partnered with Wendy's who drug test like crazy, so that's why I'm worried. I've heard they are still operating as separate entities so their policies probably aren't the same but I want to be sure. I know they're a canadian company, and I heard that canadian companies usually don't issue drug tests. But this is a US location. Is it the same in the US? Anyone work at a Tim Horton's or know someone that can put my mind at ease about this? I've been worried as hell and knowing I have nothing to worried about would really help me out.
