(note
that Canada is missing the CG... probably a typo).

Not a typo. It lists C and CF as prefixes. C is the current style, and
CF the old style still on many airplanes. It gets converted to C-FXXX
upon repaint. There are no CG-XXX airplanes.
A related funny: Four of five years ago we were flying a 180 to
Tucson, via Salt Lake. Here's how the conversation went:
Us: "Salt Lake Terminal, Canadian Cessna 180 Charlie Foxtrot India
Alpha Charlie 15 miles North at 7500, Southbound for Provo."
Them: "Canadian 180 Charlia Indie Alph...." Click.
Them: "Canadian 180 Charlie Alphia Ind..." Click.
Them: "Canadian 180 Charlia Alphia..." Click.
Them: (laughter in background): "Canadian 180, stay east of the
highway."
