So the family tried to go to the AMC in Kanata to watch X-Men 3. We did actually get to start to watch it, but about half an hour in the lights went up, and a theatre employee told us we had to evacuate the building.
We were asked to leave by one of the rear exits. When we got around to the side of the building we saw this:
The entire front of the building was cordoned off with crime tape and police were directing us away from the area.
(Apologies for the image quality — I just snapped a picture as I was walking by, in the hopes that I would not attract the attention of the constabulary.)
What I heard from someone in front of me (i.e. this is an unsubstantiated rumour) was that a suspicious package — a brief case(?) — had been found.
Update: According to The Citizen, it was a black briefcase with a black wire sticking out of it. The bomb squad “detonated” it around 23h00, but the article doesn’t indicate whether it was actually a bomb or not.
