The Canadian Taxpayers Federation fears there could be new taxes in the future for Saskatchewan residents. Prairie Director Todd Mackay says Regina may ask the Province for the right to expand into areas like gas, income and sales taxes. MacKay claims a City of Regina document states a sales tax alone could bring in about $35-million a year and there will be further analysis. The Federation says other levies the Queen City is exploring include hotel occupancy and vehicle registration. Saskatoon has no plans to add new taxes, but MacKay says the city won’t rule it out pending an audit of its current tax sources.
