WINNIPEG -- A dispute over a garbage collection pilot project could be heading to arbitration.

A city report recommended against a plan to allow city workers to pick up trash from some apartment and condo buildings.

Union CUPE argued it can be done within budget, and scrapping the pilot would violate terms of a previous grievance resolution.

Now the mayor’s executive policy committee passed a motion tabled by tabled by former Water and Waste Chair Brian Mayes to send the issue to arbitration.

The arbitration would examine whether or not the city agreed to bring the service back in house.

City administrators said the pilot would cost $2.6 million, $656,000 over budget.

CUPE said in order to find out the true costs, the pilot must be completed first.
