If there ever was a city that needed a university, it's Sarnia. Sarnia/Lambton & Chatham/Kent have a combined population of 250,000 but are a glaring gap in Ontario's university options. The closest universities are Western & Windsor which are an hours drive from Chatham and 1 1/2 from Sarnia to Windsor. and an hour to Western. Both have colleges but they obviously don't have the professional options of universities. In CK there is a University of Guelph campus in Ridgetown {about 550 F/T students in a town of 3,000} but it is very specific to agriculture and veterinary sciences so it's not an option for 90% of students.
Even a MAJOR campus of Western in Sarnia would go a long way to filling this void. If there is another new university or large campus of an existing one built in Ontario, Sarnia should be at the top of the list. Both counties have a older demographic makeup and small wonder as going to university requires all the young people to leave and once they see the delights of bigger cities, meet new friends or a partner, do their schooling with potentially an -the-job training portion, and create a professional/social network of professionals in that city in their field of study, it's very hard getting them back.
