Again the Canadian Open is on a great golf course. I've never played any of them, but Hamilton and Royal Montreal are just a few examples.
Royal Montreal has been substantially renovated prior to hosting next year's Prez Cup. I believe it just recently reopened.
It's too bad many of the other great courses in Canada can't handle an event like this, but it won't matter much since nobody is going to show up next year since it will be the week after The Open Championship. That also makes it harder to have the event in western Canada as going 5 time zones from the UK to eastern Canada is bad enough, going 8 time zones would even further reduce the quality of the field.
