I know of three at an old police station here in Brampton and I think there were more. I can't link to it on my iPod but it is on the South East corner of Queen St.and Central Park Dr.
I see... These kinda look like the old gas street lights don't they? There's still a few gas streetlights left here. It's usually either a black and a white one about 5 feet apart or simply just a larger black one. It'd be cool to score one of them that're still hanging around.
I think I have seen some gas lights downtown Toronto somewhere, they are of course only decorative and don't light up anything. And yes those are the lights.
Oh and Niall, did you mean this place? I looked on streetview and only found shoeboxes.
Still, I wonder who made these, they seem be quite unique looking fixtures lol.
