Tucked between the electric rue Sainte-Catherine O. and congested René-Lévesque, rue Tupper is a street that time forgot. Largely untouched by modern developers, it sits hidden among the unfriendly concrete towers of Montreal's Shaughnessy Village. Instead, passersby on the narrow residential street will find colourful two-storey townhomes, stained glass windows and flamboyant masonry. And one of its classic Montreal homes is now for sale.
