Ontario - Toronto - Grenadier Pond located in High Park - Apparently in the 1800'* a number of Grenadiers (soldiers) capsized their boat and drowned. They have been sighted in their boat on nights with bad weather.
Wow, of those places, I've only been to High Park/Grenadier Pond. Never felt anything eerie, even though I spent a considerable amount of time in overcast, drizzling weather walking around the pond. Not bad enough weather, I guess? :P
I had another link to haunted places in Toronto somewhere... I didn't keep it, unfortunately. Some haunted house stories, haunted subways (Yonge/Downsview Line @ Hogg'* Hollow [York Mills & Yonge]). Apparently the graves of some aboriginal people who died in wars in that area and such were disturbed during the building of Toronto'* subway system. Workers reported seeing these people and hearing noises at night.
