A report from the Manning Foundation Calgary suggests Alberta municipalities should privatize more services in order to reduce spending.
According to the report released on Thursday, Alberta towns and cities have increased their spending by 55 per cent over the past six years.
The report estimates in Calgary spending has increased by 51 percent and taxes have gone up by 31 per cent in the same time period.
The organization says that spending cannot be sustained so municipalities should consider privatizing more services.
"Re-imagining service delivery is really about consistency and efficiency," said Ben Brunnen who produced the report.
It recommends privatizing services such as garbage pickup, cemeteries and sports facilities.
"Even water and electricity could be outsourced, provided the appropriate performance management frameworks are in place at a municipal level and that's what we're recommending," said Brunnen.
The Manning Foundation released the report on the same day that Alberta mayors gathered in Calgary for the annual meeting of the Alberta Urban Municipalities Association.
Brooks mayor Martin Shield, in Calgary for that meeting, said there is a need to discuss the increases in municipal taxes.
"It is a problem because you've got now a lot of new people elected, an election just happened and there's been a lot of push back from property owners saying, how much property taxes can we afford."
In Calgary, a recent citizen survey indicated the majority of respondents would accept a tax increase if existing services are maintained or expanded.
