TORONTO - Police arrested seven protesters who occupied federal Finance Minister Jim Flaherty's riding office in Whitby, Ont., on Monday.

Durham regional police say the demonstrators were charged with mischief and trespassing.

They were released on condition they stay away from Flaherty's office or the office of any other elected official.

The demonstrators from the group People for Climate Justice are demanding greater action on climate change.

The group wants a binding climate treaty during negotiations to be held in Copenhagen in December. It also wants Ottawa to commit to reducing greenhouse gas emissions by 2020 to 25 per cent of 1990 levels.

Seven people were also arrested and charged when the same group held a similar protest last week at the office of Environment Minister Jim Prentice in Calgary.
