According to CBC, it's a police station compound in the north end of the city. He'll be moved later today to another detention centre.There is a video at this link and unfortunately, I don't have speakers. They have a shot of the detention centre? Do they mention the name? If not, do any of the locals recognize it? There is one close to me but have never driven by there.

And for anyone listening to that link, the SUN is still (after the guilty plea) saying his lawyer is Marc Labelle instead of the correct Pierre Panaccio.
