When I was driving for a company in Vaughan I kept seeing this ratty looking street from the 407, you wouldn't see it from a car as you're sitting too low to see over the barrier. Anyway, me and my girlfriend went to check it out on a weekend sometime last year. There was around 5 abandoned houses (maybe more now?) on this creepy "The Hills Have Eyes" kind of creepy, street.
Its really easy to get to, surprised this isn't on here, or maybe it is?
Would love to see inside these houses, but I'll leave that for the pro's.
UPDATE by electricfuneral
Went by here today to check out the street, but none of these houses are abandoned.
