Double pole base?
I don't understand the purpose of having this pole base. The button I think is a bulldog but its a push button. The west side of the GTA uses these different mounting doohickeys as seen on the signal on the left.

that's a breakaway base. If the pole is hit, it will fall down so that way the engine of the car doesn't end up on the driver's lap.

A weird looking one too , the usual ones are either breakaway nuts with a aluminum cover or a cast aluminium box.

Looks similar to what Massachusetts uses for their state-owned guide signs here. Here's a pic. RIDOT use uses U-channel poles for guide signs off the freeway (and some on the freeway) like this.

There's a few intersections in Brampton with those signal doohickies Model25. They're called astro Brackets. See: this link

Another common use for the Astro Bracket is mounting a second signal on the same arm.

I forgot that we had about 3 or 4 intersections that use these. I personally really dislike the way they are mounted and used in Brampton

LOL yeah they look a little weird. I think the cast aluminum breakaway bases look nice with traffic signals. The traffic signal poles here are not breakway though so if they get hit they don't go anywhere. They can get hit pretty hard and all that happens is a dent is left with a little bit of colorful scratches that match the paint color on the car that hit it.
