Construction noise at 1am, 2am, 5an ...

I live at 197 Yonge Street. Toronto, on. There is a construction going on at Yonge and queen for months now. They make extremely loud noises all the time. They start work at 5 am. It's 2 am now and they're still making very loud noises. It's during me crazy and it doesn't let us rest. Isn't there anyone to remind them of construction laws and people's right to rest??!!!!! This is ridiculous. Someone needs to stop them.
