This aluminium and glass complex (1982) incorporates, on the Rue Sherbrooke side, the façades of a row of greystones dating from 1872. One of these, Strathcona Hall (1904), was sold by McGill University with the stipulation that the hall be preserved. It collapsed during construction of Place Mercantile, but was entirely rebuilt. Today the building houses the offices of Cacades Inc., Cascades Etcan Inc., and Etcan International Inc.
