But the passage of the bylaw faced tough opposition last week when city councillors sat to discuss it. Opponents tabled a 1,500-name petition against it.

'This is absolutely extraordinary in the wrong way,'' said lawyer Gabriel Gaudet who represented those opposed to the bylaw.

The lawyer, who didn't rule out challenging it in court, said one of his clients, a contractor, fears he will lose business if homeowners cannot do renovation work or repairs Sundays.

'The mayor really went overboard with this and I will fight him until he changes his mind,'' the contractor was quoted as saying.

The mayor said those who complained against noise must keep in mind that they can be asked to appear in court if anyone who is fined goes to court.

'This way moaners will soon realize that they can't call police if their neighbour makes some noise for five minutes,'' he said.
