I looked everywhere for one and couldn't find one. I went to the dealership and they repaired mine. Cost me about $107. A year later, it was malfunctioning again, so I went back to the same dealership and they replaced it. They cut me a deal since the previous repair didn't last.
I think that if the cars in the U.S. were required to have DRL modules, these things would be all over the place, but since it's just us Canadians, good luck finding the part anywhere other than a dealership.
