I wonder what brand are the signals, they seem to look more like Fortrans than CGEs.

They look like CGE's to me. But you made me think about that though.. The back of the 12-8-8-12 looks like fortran. If the 12-8-8-12 was CGE there would be a visibly bigger part to the top
and bottom

Also does the light on the right on Airport road look like a GE M400-A or a Model 25? Its really hard to tell but im guessing a GE M400-A

Yeah the CGEs have a much deeper back. I wonder if the light on Airport road is a B2255. I think it's a Model 25 though as MTO didn't install a lot of Powerlites in the 80s and 90s.

Yeah the quality isnt the best to tell what it actually is. As for the traffic signals it could potentially be one of these. This is the only one of these signals ive ever seen in Peel Region. Not sue what it is exactly. Its on the same road too.
