Your car looks familiar so I decided to check on my old hard drive & I found an ad from 2015 where a car that may have been yours was for sale in Beamsville, Ontario (near St. Catharines). A Ram Air III 4-speed car (!) sold new out of HMP in Hamilton, Ontario. Note that Ram Air III does not necessarily included a functional ram air setup (separate option on top of the RA III engine).

The colour looks the same as your car but the T/A rear spoiler is not present. The inserts for the hood scoops are black like yours as well (!). The car was originally Mayfair Maise (light yellow). Rear antenna. Power windows. Console & wooden shift ball. Standard interior but with a grab handle & woodgrain on the dash. RHS mirror added at some point. Is this possibly your car at an earlier time?

The Kijiji ad was from 2015 and stated that the seller had bought it in 2014 from the previous owner who had owned it since 1980.
