Windsor: yes - EC Row Expressway
London: yes - Highbury Avenue
Guelph: no - Hanlon Parkway is provincial and it’s only 70-80 km/h
Hamilton: no - Linc is 90 km/h and Red Valley has been downed to 80 km/h
There’s an extra one: Ottawa - City Road 174 after the split.
Lol you know what they all have in common? They’re all downloaded provincial highways.

EC Row = Highway 2
Highbury = Highway 126
Gardiner = QEW
The Queensway (east of the split) = Highway 17

Sudbury can definitely up the speed limits on RR 55, RR 35 and Maley Drive Extension from 80 or 90 to 100, and look: I just mentioned 2 former provincial highways!
