The City of Ottawa says more than 100 stop signs have been stolen since the beginning of the year in a potentially dangerous trend.
City officials say thieves have stolen 19 signs from their posts in the last week alone, eight of them stop signs.
"I think it's absolutely bloody ridiculous and somebody's going to get killed," said resident Wayne McCall who has noticed signs missing in the Stittsville area.
'God knows what could happen,' says El-Chantiry
Residents and city officials alike are concerned about the consequences.
"Whoever thinks this is a funny game, we don't think it's funny game at all," said Eli El-Chantiry, councillor for West Carleton-March.
"If you are going 80 (km/hour) and you miss a stop sign, God knows what could happen."
Missing stop signs are considered an emergency and are immediately replaced, but there is no such criteria for other signs like speed limits and road names, said El-Chantiry, who also chairs the police services board.
Call 311 to report missing signs
The City of Ottawa is now warning the public to be on alert for sign theft.
"If you see a missing sign, please call 311 immediately," said El-Chantiry. "But if you see people taking the stop sign illegally, call 911. This is a crime in progress."
