The National Inquiry into Missing and Murdered Indigenous Women and Girls wants to see the creation of a national police task force.
The recommendation came Wednesday as commissioners released an interim report on its work.
Chief Commissioner Marion Buller says families want to know what happened to their loved-ones.
A police task force, if created, would have the ability to reopen and review cold cases, something the inquiry panel can not do under its mandate.
Commissioners say families should have a say in the make-up of an national police task force.
The interim report also blamed federal red tape for an eight-month delay in setting up its offices.
It says federal restrictions seriously hampered the inquiry’s ability to contract people and services.
