I received this link from one of my Canadian racer friends.

It says one of seven, but my friend who is my age and lived in Canada all of his life says he knows for a fact that at least 25 were built, maybe 30.
Mostly 2 door sedans, but several hardtops and at least one convertible.
Just some more Hipo history.
