Well, I guessed August and I'm thinking it'll be at the Toronto East Service Center (little use to me). Probably the easiest from a siting and electrical servicing perspective.
The first (Ontario) priority should be the Hwy 401 corridor from Windsor to Montreal. I'm not clear why they are prioritizing the section east of Toronto when I would bet there is more overall traffic on the western section. The western section is an important tourism route to/from the US into Canada. (I don't have actual traffic flow numbers, but would be interested in knowing the utilization levels on the various 401 sections)
