There's some really old stuff in some parts of Toronto.
The oldest probably being the
Palmerston Blvd. lights. They were erected sometime around 1905-1910 and were originally fitted with incandescent. Later refurbishments saw the poles repainted, the globes replaced and interestingly the original incandescent retrofitted to use 70w PSMH with the ballast located in the pole base.
Some other stuff include:
