Canada's information and privacy commissioners are urging the federal government not to trample on civil liberties in fighting terrorism.
In a joint statement today, they call for an evidence-based approach when adopting any new laws to combat extremism.
They also say Canadians should be consulted on the need for any changes, as well as their scope and impact.
The ombudsmen are holding their annual meeting in Ottawa.
The federal government is contemplating new laws in response to the recent attacks that killed two soldiers in broad daylight.
It has also introduced long-promised changes to strengthen the ability of Canada's spy service to probe terror suspects overseas.
