The speed limit would be staying put not because the road can't accommodate faster speed but the volume is too much to support it during most times of the day. 120 to 130 is possible on 69/400 north of Barrie where traffic is light but it's too fast for busy routes where some don't even drive at 100.There are several highways in US and elsewhere with much lower safety standards (narrow right shoulder, no left shoulder, short merging lanes, etc), yet much higher speed limits.
Even 401 within GTA is good for 120 speed limit. All merging lanes are 300 m long with a few exceptions and there are wide right and left shoulders pretty much everywhere.
