As of midnight Tuesday night, all leftover campaign posters will technically be in violation of Quebec's electoral law.
Political parties are supposed to remove them 15 days after an election. Failing to do so may cost them money.
The province's municipalities give parties a five-day warning to remove their campaign signs after the 15-day period has expired.
If any signs are still up following that period, the municipalities remove the signs themselves, and then send the bill for labour and expenses to the parties.
The Quebec Election Act doesn't provide for fines for tardy removal of posters.
In Montreal, the work is done at the borough level.
A city spokesperson says the parties usually cooperate within the time frame given.
