I was reading an old copy of Muscle Car Review at the cottage this weekend and came across the story of the Canadian versions of these cars

Apparently 20 or so of these cars  were ordered to do pace car duties at the 1967 Canadian Grand prix since 1967 was the year of expo

note that the cars themselves were not made in Canada but there are some details that make them unique
