This link shows all the Greyhound locations in Ontario - JUST Ontario.

I also checked how many buses per day go from Sudbury ON to Toronto (and there are 5 Toronto destinations).

There are thousands of locations in Canada, most with at least 3 schedules passing through them.

So in 8 years, including this week, 5 incidents of violence have occurred among thousands and thousands of trips and routes.

I'd take Greyhound again. The chances of harm are pretty slim - and it's safer than driving my car all that distance (though a tad hard on the tush! )
