Transit users in Laval are being asked to watch out for service disruptions and cancellations expected throughout the day on Tuesday.
The Société de transport de Laval (STL) blames the disruptions on what it calls illegal pressure tactics by the bus drivers' union.
According to the STL, nearly 150 trips had to be cancelled on Monday, leaving more than 2,000 customers stranded.
It adds that some drivers have hesitated to follow a directive to refuse overtime.
The employer claims that the union's actions violate a safeguard order by the Administrative Labour Court, decided last November.
Legal action is expected to be taken Tuesday by the STL to stop the pressure tactics.
To end the labour dispute, the STL says it proposed last February that it call in an arbitrator, which it claims the union refused.
The collective agreement of the STL's 625 bus drivers, who are members of the Canadian Union of Public Employees (CUPE), affiliated with the FTQ, expired in August 2019.
The dispute is mainly about wages and inflation.
The STL, which covers more than 1,400 kilometres in Laval, reported two weeks ago that because of the COVID-19 pandemic, its ridership has still not reached 60 per cent of its usual level, and revenues are suffering.
