Designed by architects Roger D’Astous and Jean-Paul Pothier, the 38-storey hotel was part of the Canadian Pacific hotel chain and was the tallest hotel in Canada. Fifty years later, the iconic modern landmark with arched outward-curving windows (operated under the Marriott hotel chain since 1995), is still endearingly referred to as “the cheese grater” by many Montrealers. The 28-storey Place du Canada office tower, which was part of the same complex, opened a few weeks later.
