Arnprior - Deep River (freeway to Petawawa, dual carriageway to Deep River) Mattawa - Sault Ste. Marie, Nipigon - highway 11 split (twin highway 102 as well, no point taking the longer 17 route), and Kenora to the border. I wouldn't mind some sort of connection to I-75 and the Twinning of 61 south of TB either, as well as some sort of Sault. Ste. Marie bypass.
Stratford to highway was done up as an upgraded regular road, not to be done as a 400 series highway. a mix of 4 laning and dual carriageways. I think they wanted a singular new interchange with a couple of lights still mixed in if I recall correctly. 6 is probably fine as a 4 lane road, upgrading it beyond that will really start to attract sprawl. Maybe add an interchange with Dundas.
Agreed on 7 to Perth, build it to 400 series standards IMO.
another priority should be to upgrade 11 south of Orillia as well, its a 4 lane RIRO that sees 40,000 AADT. Get an HOV on the 400 all the way to Barrie as well.
Yes but is the first link HSR or a freeway? its a freeway. you may see regular rail connections such as VIA or something, but that is hardly a "superior" option. Its the rail equivalent of a 2 lane 80-90km/h road. The first thing to hit a city normally is a 4 lane freeway, not 200km/h rail with hourly frequencies that is required to make it a "superior option". Even in if you were correct, travel in the north is so decentralized that a freeway is the only real way of dealing with it. I'm much more lenient with it in southern Ontario, I would rather somewhere like Stratford have a strong rail link than a freeway, but up north its a completely different context.
