Manitoba Premier Greg Selinger says the Manitoba government ran the numbers on a sales tax increase before the 2011 election, but did not seriously consider it.

Selinger is responding to newly released Finance Department documents that show there was some analysis of a PST hike in 2008 and 2009.

The documents were obtained by the Opposition Tories, who say they now have proof Selinger was eyeing a tax hike even as he was promising not to raise the tax in the 2011 election campaign.

Selinger says Finance Department officials analyze all kinds of potential changes every year, and the sales tax idea was not considered by cabinet at the time.

The government did raise the sales tax in 2013 to eight from seven per cent.

Selinger says he made that decision weeks before the budget, due to the cost of flooding and a continued economic slowdown.
