Are they open in the summer too?

I was recently in Toronto and can see where I was on the map, but I had no idea there was anything underground nor any obvious big accesses to it etc.

Yes. PATH isn't particularly well marked or easy to navigate. It just feels like you are walking through a series of interconnected malls and hotel basements.

		It's also useful during the summer if it gets unbearably hot outside (for me, over 25C). The PATH is typically much cooler than that.
