The provincial government intends to increase consumer hydro and Centra gas rates by about three per cent in December.
It plans to bypass the normal regulatory process to do it, saying it is too expensive.
Normally, hydro, natural gas and auto insurance rates are set through an independent third-party process controlled by the Manitoba Public Utilities Board.
The government introduced legislation yesterday to implement the rate hike, raising concerns from consumer advocates and opposition politicians.
NDP Leader Wab Kinew calls the move "very sneaky" and says his party will do all it can to prevent the passage of the measure.
