Just found a new one while talking in Facebook in the Old Ottawa And Bytown Pic's site
Horner Motors on 430 Gladstone Ave in Ottawa. Present owner has the sign with Star crest in upper left, Road King crest lower left. Durant crest upper right. Can't get him to show the full sign.
He says .. The floor is reinforced concrete and there was a ramp that allowed the cars in the building...Technically one could open a car dealership there today.

Do You own a car built by Durant? 1932 614 sedan made by Dominion Motors
