			Quebec is a very special city, but I am wondering why no single American race, not even the Tour of California, can attract such a high quality field? The start list reads one of a major historical classic continental race! 
Is it just the money?  How much did it cost to get a ProTour race for the city of Quebec?
Are american sponsors just cheaper?
		
		
	 
There are probably a few reasons. Charly Mottet might have something do with it. He probably has a working relationship with many of the directors/managers, both as a rider and organizer. Some of the DS's/managers may have raced the Montreal World Cup as well, that probably helps. Montreal also has a history of high-level eventsl...Olympics/Worlds/World Cups. 
Culturally, Canada, particularly Quebec, has closer ties to Europe than the US does. Quebec still feels a strong affiliation with France...at Quebec city's 400th anniversary there were French politicians in attendance etc. 
US sponsors are not cheaper, but Quebec based businesses are very European in their attitudes towards sport. It doesn't have to have a ball or a stick for them to get behind it, despite the popularity of hockey. Lastly, look at the composition of the Canadian National team for these races...only one non-Quebec rider. Quebec is the home of cycling in Canada...Ontario and BC are second. There is very little in the other provinces (Alberta has maybe  a little more than very little...).
I should add that Dutchsmurf's reason of calendar placement has merit as well. End of the season is probably the best time for North American racing for the Euros.
