Thunder Bay and Saskatoon Terminals are both Class E airspace surrounding a Class D Zone. It's treated as a very bastardised version of Class D airspace by the controllers
Not for much longer. Word has come from the suits in Ottowa to stop bastardising it and treat it as Class E was intended to be. In other words no service to VFR's and just traffic info to IFRs on VFRs. The party's over.
