I think using the Hespeler Sub north-east to Guelph would be a much better proposition, and put a station in Cambridge closer to downtown and the track is already there, just needs refurbishment.
You could simply extend one or two of the existing Georgetown terminating trains into Cambridge instead of going to Kitchener.
That would be the Fergus Spur, not the Hespeler Sub - it's the last remaining part of the CN Fergus Sub that ran between Lyndon and Palmerston (via Galt, Hespeler, Guelph and Fergus).
That track is in poor shape, with very few freight customers remaining in Cambridge. It would be better off as a recreational trail than a GO corridor in my opinion.
