To my eye it looks Soviet block in styling.

Nice little car.  It would definitely be the only one you'd see at pretty much any car show, for sure.  They sure did rust quickly around here, though.

The original dealership was located on Prince Albert Road in Dartmouth, and built around 1930 (designed by architect Herbert Elliot Gates: https://dictionaryofarchitectsincanada.org/node/1585).  The buildings are gone now, having been torn down and replaced with residential.  I last remember it being used in the 1980s for a Skoda dealership.

Here's a dealer tag on ebay (a hundred bucks US seems a little stiff): https://www.ebay.com/itm/402702854120

The dealership was bought out and the name changed to Forbes Chevrolet-Oldsmobile Limited in 1967.  http://akama.ca/company/Forbes_Leasing_Limited_a40eb3146846.html

"The Forbes Group was founded in 1967 by Ivan L. Forbes when he acquired Teasdale and Foote's long standing GM operation and established it as Forbes Chevrolet-Oldsmobile Limited on Prince Albert Rd in Dartmouth. Forbes Chev-Olds evolved over time to become a standard for reliability, trust and integrity in the automotive marketplace. The business moved to Portland Street in 1969 and Ivan was joined by his son Patrick W. Forbes in 1970 who took over the business in 1984."

Here's a video that shows the dealership in the 1940s.  There was a larger stone building in back that I believe held the showroom and would have been the one designed by the architect above, I imagine.  Don't have much more solid info than that unfortunately.

The dealership was located where Starr Lane is at the google link:  https://goo.gl/maps/hEwY3aaBNkg1jhSY6
