Probably the most visible attraction in Toronto is the CN Tower. I wonder if they had plans to try to topple it.
About two(2) weeks ago I had a phone survey about touring Ontario Canada and Toronto in particular. When I mentioned something about crime and terrorism, the survey taker seemed to imply that was a growing reason for the recent fall in tourism. Toronto used to be considered a very safe city. Just a quick reading of Canadian newspapers and you will see stories of not so nice things happening near and around Toronto. It's still a very nice city but not the utopia it was once believed.
