The above-linked Ghost Tours are something I would love to try.
I know that I have had a lot of fun going on ghost walks in different areas: Fort George, Kingston, Ottawa, Montreal...
My favourite, however, is that of Ottawa:
Haunted Walks of Canada was founded in 1995. It offers unique historical walking tours with a ‘ghostly’ theme in Kingston and Ottawa, Ontario. Our tours appeal to all age groups and are conducted in the evening when the lights are low and the atmosphere is just right for a good ghost story. The Haunted Walk captures the unique ‘darker history’ of each city by presenting it the way it was meant to be seen.
The Haunted Walk offers several different walking tours through the quiet streets of the Nation's Capital. We are Ottawa's most popular walking tour company and this season, we are expanding with several new tours. Whether you're interested in chilling murders, or misbehaving ghosts, you can join us in the daytime or in the evening by lantern-light.
