In the case of the Old Winnipeg, I was wondering if the infrastructure might be better as compared to today. Proportionally, wouldn't more money go to building suburbs and repairing streets that connect downtown with the suburbs? A de-amalgamated Winnipeg could possibly mean infrastructure spending being spread more fairly, if it isn't already today.
It seems to work well for Vancouver, each city in that CMA maintains its independence while Metro Vancouver Regional District oversees development in the region.
Overall, it seems that unicity is viewed as a failure, many seem to argue that it resulted in the suburbs taking over the development of the entire urban area.
