Dick, I stand corrected, I was thinking high level enroute in the USA. Canadian radar coverage would equate to at least 80% of the whole Australian land mass.
However, you mention Whitehorse (CYXY) up in the Yukon. CYXY IFR aircraft are put sequenced onto instrument final by a procedural sector at an ACC, the aiport has a manned TWR with a discrete TWR and Ground freq, when not manned VFR and IFR traffic (after being cleared for an instrument approach by "centre") are on a discrete flight service freq.
Canada has Flight Service Stations (FSS) at airports that warrant a traffic information service but not an ATC service. Australia chopped Flight Service relatively recently*, are they making a comeback???
