Montreal's inspector-general will look into suspicions raised in the city's auditor-general's report of possible collusion or corruption in the snow and garbage removal industries.
The report looks at contracts awarded over the past nine years across the city and found evidence of possible price-fixing and contract rigging.
Nothing has been proved yet and the city is warning Montrealers not to become overly cynical while the investigation is pursued.
But executive committee member Pierre Desrochers says the findings did surprise him.
He added that it's too early to say what, if any, actions the inspector-general will recommend.
But he said the city will act if necessary.
"If measures need to be put in place, we definitely will put strong measures in place to ensure people have confidence," he said. "That's why we were elected: to regain that confidence, to rebuild that confidence in the city."
He added that the city is already adopting some measures to examine the way contracts are awarded
