Dominique-Ducharme Building (formerly Montreal Customs Building)

The Dominique-Ducharme Building, located in Montreal, is an eight-storey Beaux-Arts structure occupying a full urban block, built in two phases (1912–1916 and 1934–1936) based on E.L. Horwood's original design. Its two wings feature a uniform façade of Stanstead granite and Wallace sandstone.

A comprehensive assessment of the building envelope was first carried out to determine the extent of deterioration and the risks to public health and safety, leading to emergency work ahead of the major restoration campaign.

Masonry restoration was carried out in three phases, from May 2019 to February 2023, followed by a fourth phase for the installation of a new universal access ramp, completed in November 2023.
