Upon arriving, we sensed that it would be a great experience. Not unlike a great-house. After a long and somewhat pleasant walk through the woods, we finally arrived at the main manor only to notice a tour entering the house. We find out inside the office that we needed to arrive early to join the tour and, even though they had just started, the person in the office would not let us join that tour and that we would have to wait over one hour (no self guided tours allowed).
Unless you call ahead, good luck getting to see the main house. If you speak only English... Tough luck. There are only 2 tours available per day. The staff working the office is less than friendly and not very helpful.
Also BEWARE of tons of poisin ivy along the path leading up to the house. Parks Canada did not bother removing these but rather erected a sign. Nice effort guys.
The other houses that we could visit ourselves were ok... But basic.
So much more could be done here. I recommend that you visit elsewhere.
