The café was in Business in the 1960’s and 1970’s but the building changed to full residential later on. The SM is a North American model (North American rear license plate lighting and side marker lights). I cannot tell if the SM is a 1972 or 1973, but I think I see a bit of a headlight glass cover. If this is right, then it is most likely a 1972 since 1973 Canadian SM's had the USA sealed beam headlights without the glass covers. The other car is a 1971 Chevrolet Impala, apparently a Canadian model since it has no side marker lights.

The photo most likely was taken in the mid-1970’s.
