Busses in Saskatoon could come to a halt in just 48 hours.

The City of Saskatoon filed a lockout notice to the Amalgamated Transit Union 615, which represents the city’s bus drivers, Thursday — meaning busses may stop running starting Saturday night.

The notice comes after 11 months of failed contract negotiations and the union’s recent rejection of the city’s final contract.

“The decision was difficult and not taken lightly, but we need a contract,” said Marno McInnes, the city’s director of human resources, in a media release.

Bus drivers have 48 hours to respond to the lockout notice, according to the city.

“It is important that transit users make alternate arrangements well before 9 p.m. Saturday… in the event of a lockout,” the release stated.

Access Transit — a service for people unable to use the regular bus system and which uses lift-equipped buses and cabs — will continue operating as normal.
