Come fly with us! (for a one day vacation), a Grouse Mountain poster calendar from either 1980 or 1986 based on calendar dates, although I think the aesthetic is more 1980, and if it was 1986 they probably would have made some sort of Expo reference. More about the history of the tramway from wikipedia:

The tramway, known as the Blue Tram, was built by Austrian steel company Voestalpine and was opened and inaugurated on December 15, 1966, by Premier W. A. C. Bennett.

Ten years later, the mountain was purchased from its original owners by the McLaughlin family in 1976. The new ownership provided additional funding for the construction of a second aerial tramway, built by von Roll, known as the Red Tram or Super Skyride, that same year. The Super Skyride, using much larger gondola cars holding several dozen passengers, is now the main tram, arriving at a separate top terminal building a short walk from the lodge. The older Blue Tram is now mainly used to transport staff and supplies directly to the lodge structure.

Update: Not really an update; I’m just having second thoughts. I might not have picked up on some clues. The typeface for Grouse Mountain is very Expo86 inspired, and the fact that the gondola becomes a jet aircraft fits very well with the transportation theme of the transpo Expo. This also falls during the summer months at Grouse, right at the peak of Expo 86; maybe this WAS from 86!?

Update 2! I just learned from the artist himself! This is a Bob Masse original design!
