^It looks really nice, but I am not sure if it is worth (almost) 7 million US dollars...
That said, I would consider it, if I had that kind of money
It's 12,000 square feet according to the article, and has a driveway that can accommodate 10 cars. This photo doesn't show the entire property.
Not that I'm saying it's worth that much money; it depends on what shape the guts are in (heating, plumbing, electrical, etc.) and if the foundation is solid. Oh, and mold and asbestos would also be a concern.
But it looks just like the creepy gothic mansions in some of the computer games I've played, not to mention the house in the Fighting Fantasy gamebook
House of Hell (which I've never finished during the last 35 years due to the frustratingly complicated multi-level map that has to be drawn accurately on graph paper so you don't get completely confused and end up dead... that's one I started novelizing a loooong time ago, even though I haven't solved it yet).
I really like this room: (but they took all the paintings out, which comes across as cheap...)
Not sure about the location, though. Seems to be some gated community. A castle should be away from other buildings, preferably on a hill.
It looks like the paintings were replaced with posters of wine bottles. That room looks absolutely claustrophobia-inducing.
Honestly, if I were to buy that place, I'd turn it into a gothic-themed LARP or other RPG-type attraction. They didn't post photos of the bedrooms or bathrooms or the stairway in the tower, so I can't say whether those would be a plus or minus.
I do like the front hall and stairway, though.
All this said... Ontario lacks the Rocky Mountains, and while there are some very scenic areas of that province that I'd like to visit, it's not a place where I'd want to live.
