So we'll have to ban Canadians from entering he country now.

Linked is an actual local news report, with the following:

" A witness who asked to remain anonymous told Radio-Canada that two masked individuals entered the mosque. "

"It seemed to me that they had a Québécois accent. They started to fire, and as they shot, they yelled, 'Allahu akbar!' The bullets hit people that were praying. People who were praying lost their lives. A bullet passed right over my head.

I'm not assigning/promoting any motive to the attack, the attackers may well have been perpetrating a ruse themselves. Just don't jump to conclusions/conjecture,,,, as I can assure you the press has and will, even this submitted article to a degree,,,,,,,,,, just yet.

Neither of the two men who were detained was previously known to police, authorities said.

So their intelligence systems were incompetent or looking in the wrong direction?
