About 200 police officers spent Tuesday morning protesting outside the office of Suzanne Roy, the mayor of Sainte-Julie and president of Quebec's union of municipalities, who spoke out last week in favour of proposed pension reform legislation.

The legislation, Bill 3, would see municipal employees and cities evenly split the cost of pension plan deficits, which taken together are estimated at around $4 billion.

Last week, Roy criticized the mayors of a number of Quebec municipalities for speaking out against Bill 3.

She said that Quebec's municipalities had an "obligation" to stick together in favour of pension reform or risk leaving taxpayers on the hook for the paying down the deficit.
