I've often wondered what it would take to re-lay the tracks of the Branchton sub, which splits off the CN double track mainline southeast of Cambridge near Lynden and Governors roads* and heads all the way in to the Ainslie street terminal. Very little of it seems to have been developed on, it's still mostly greenfield. It would effectively make Cambridge a new destination on the Lakeshore West line, splitting off from the Hamilton/Niagara service at Burlington bay. Google Maps / back of the napkin research shows Grand River Brewing and a few small residences on Ainslie to be about the only things affected...
* Technically it's the old Brantford bypass that splits off here, with the Branchton sub splitting off that in Harriston
