Outside of Toronto, on the way to Niagara Falls is the small city of Hamilton. In particular, there is a lot of industrial infrastructure, and also the largest Radio Tower in Canada - which once stood at 1173 feet (demolished and relocated in 2024).
Its actually terrifying and awe-inspiring to stand under the tethering cables of the tower. My photos can only give an idea - but not really express it (you just have to do this in person).
Also strangely: there is a residential neighbourhood right beside the tower. Not sure if it adds or subtracts from the value of the land around it.
