I had the same problem with the people across the road, a pounding "doof doof" right through my house, I didn't really have a problem with it until they decided it would be a good idea to crank it up at 2am one morning. Anyway, one phone call to the police later and I've not heard a single "doof" since. Don't know why the Canadian authorities don't want to act, as it is their job to keep the peace.
