Ontario's Premier has called off negotiations with aboriginals protesting at a development site near Hamilton, saying the group's increasingly violent actions make it impossible to work together.
"A condition of our being at the table was that public safety would not be compromised. In fact, last Friday it was - without a doubt - compromised," Dalton McGuinty said in the legislature.
"We are no longer prepared to continue negotiations."
Mr. McGuinty said the province would only return to the table when the barricades at the disputed site come down and if aboriginals help with the police search for seven people in connection with recent skirmishes at the standoff in Caledonia, Ont., southwest of Hamilton.
Earlier Monday, Mr. McGuinty said the violence by the Six Nations people at the standoff has tried his patience.
"We have just about exhausted our goodwill and our patience," Mr. McGuinty said.
Asked what he'll do if the barricade doesn't come down soon, Mr. McGuinty simply answered: "We'll see."
Warrants were issued after an elderly couple's car was swarmed and two news cameramen from a Hamilton television station were assaulted on Friday.
"I'm very pleased that warrants have been issued.... I was angered and deeply disappointed that these particular individuals did what they did," Mr. McGuinty said.
The Six Nations started their occupation of the Caledonia housing development in February. The aboriginals claim that parcel of land belongs to their ancestors.
Attempts to end the dispute through peaceful negotiation haven't succeeded and tensions have been mounting among protesters, local residents and police.
The issue of how governments, and police, should resolve aboriginal protests falls under the shadow of the deadly 1995 Ipperwash crisis.
A police shooting resulted in the death of native protester Dudley George and an ongoing inquiry into that incident is investigating what role government played in directing police.
The opposition Conservatives have accused the McGuinty Liberals of failing to show enough leadership to help resolve the issue.
Mr. McGuinty recently countered that the preference of the Conservatives would be a show of police force - an apparent reference to how the previous Conservative government under former premier Mike Harris has been accused of handling the Ipperwash dispute.
Lawyers for Mr. Harris recently warned Mr. McGuinty that he's risking legal action if he makes statements that allege Mr. Harris issued direct orders to police at Ipperwash.
At the Ipperwash inquiry, Mr. Harris testified that at no time did he direct police actions.
