Ontario Advanced Education Minister Deb Matthews' office says she has no authority to condemn a ban on polarizing events at a Catholic university in Ottawa that used the policy last week to cancel the scheduled screening of a documentary about abortion.

A Catholic university that cancelled a screening of a documentary about abortion receives millions of dollars in public money each year but Conservative Leader Andrew Scheer is staying silent on whether he would strip funding from the school if elected prime minister.

A Catholic university in Ottawa cancelled a contracted screening of an award-winning documentary about a doctor who provides abortions at sea, telling organizers two days before the screening that they could either change the film or go somewhere else.
