Some 45 Edmonton officers erected a fence around the camp in Alberta's provincial capital and began ordering people out as they took down tents, the Canadian Broadcasting Corp. reported.
Three people who refused to leave were charged with trespassing although there was no physical resistance, police said.
The group has been on privately owned land since Oct. 15 as an offshoot of the Occupy Wall Street movement in New York that decries corporate greed and income disparity.
A development company owns the Edmonton land and reportedly expressed safety concerns based on the protesters' use of wood stoves and campfires, the CBC said.
Hours later, Montreal police moved in on that city's Occupy site and began tearing up tent pegs as protesters jeered them, the CBC said. No arrests were reported.
Earlier this week, police shut down Occupy tent encampments in Victoria and Vancouver, British Columbia; Calgary, Alberta; Quebec City and Toronto.
