Mayor Brian Bowman wants to know how much pot legalization will cost Winnipeg.

The mayor tabled a motion at council Wednesday calling on city staff to study the implication of the federal law that comes into effect a year from now.

Bowman said on top of policing, there could be other costs associated with oversight and regulation.

The mayor added he hopes tax revenue from the sale of pot will be used to help cover the related costs.

Premier Brian Pallister is urging the Trudeau government to delay implementation until a lot of these issues are worked out.

Bowman also tabled a second motion, asking the city to consult with the province on how revenues from a future carbon tax could be shared with Winnipeg.
