The province denies the OPP failed to enforce the law in Caledonia during a native standoff and to protect a family whose home borders the occupied land.
That claim is part of a statement of defence by the province in a $12-million lawsuit launched last September against the OPP by Caledonia residents David Brown and Dana Chatwell.
The couple claims, among a host of other allegations, that the OPP breached its duty to protect them by allowing natives to harass the family.
In court documents filed in December, the Ministry of the Attorney General says the OPP acted with all due care in performing their duties and responsibilities.
"The defendants deny that the OPP ignored the plaintiff's 911 calls or other calls for assistance," the ministry says in its defence.
Brown and Chatwell, whose Argyle Street house borders the former Douglas Creek Estates, claim the OPP failed to protect them from native intimidation, trespassing and threats of bodily harm.
Their allegations have not yet been tested in court.
The couple also claims the OPP secretly installed a hidden surveillance camera inside the family's home after a break-in because police believed they had vandalized their own home.
The government claims the OPP took all reasonable steps to prevent crime and breaches of the peace and to protect the family. It also argues police respected the rights and freedoms of the protesters, residents and all other stakeholders.
The OPP took appropriate steps to "facilitate the peaceful resolution of the protesters occupying the (Douglas Creek Estates) lands, help create an environment in which productive and respectful negotiations may occur, and preserve the rule of law in Caledonia," according the statement of defence.
"The Crown demonstrated the utmost good faith and exercised its discretion ... to the protesters, the occupation of the DCE lands, the residents of Caledonia, the circumstances of the plaintiffs, and the public at large."
