Grizzled. Yes Canada has it sorted out. Large areas without radar coverage yet low level class E in many terminal areas. I have flown extensively both IFR and VFR studying the airspace in Canada and the USA.
Wrong!
Not one designated Terminal in Canada is Class E airspace.......
Low level Enroute sectors have absorbed airspace such as Saskatoon, Regina and Thunder Bay. They are controlled by Enroute controllers, using radar, not Terminal controllers.
