Cool pics, I didn't know Brampton also converted the CGE peds to countdown like Toronto did too.
The CGE peds had at least 3-4 different variations in the design too. The first one (1950-1960?) had a smooth top and bottom and a GE logo centred on the back. The 2nd type (1970s) had a bumpy top and bottom and the GE logo on the back was moved closer to the top. Also the text "Made in Canada" was added too.
The 3rd type (1980s) looked like the 2nd type but the GE logo was replaced with the CGE logo in a rectangular box. The 4th type was made by Fortran so it had a Fortran logo on the back but it still looked the same as the other CGEs.
On the stretch with the highmasts, I wonder if MTO is considering widening it, I think it gets pretty congested during rush hour.
The shoeboxes are quite rarely used as streetlights in the GTA too, I think Erin Mills near the 403, and North York near the Yonge/Sheppard and Yonge/Finch area are the only other places that still have them.
