What are you basing that on?
The 2009 environmental assessment identifies a number of improvements necessary for two-way all day service
http://www.gotransit.com/public/en/docs/ea/georgetown-kitchener/Rail_Expansion_ESR.pdf
These include adding a 3rd track on sections shared with the CN mainline, adding a 2nd track on most of the rest of the line, adding signals, straitening out a curve, replacing a few junctions, etc. The report identifies the specific objective of increasing the maximum speed to 80mph (128 kph).
80mph is below the existing maximum operating speed of GO locamotives of 93 mph (
http://www.gotransit.com/public/en/docs/publications/quickfacts/Quick_Facts_GO_Trains_EN.pdf) so there is no need for new rolling stock and express trains from KW can share track with other go services and VIA trains.
I guess it depends what one's definition of "high speed" is, but wikipedia identifies a number of sources that set a 200kph minimum. If that's what the premier means by "high speed" then a whole new set of upgrades are necessary, including new rolling stock (such as a Bombardier Jettrain), additional grade separation, additional safety features and probably a lot of new track (so these new trains can bypass slower moving GO, VIA and UPExpress trains).
