No. 155 Cumberland – 155 Cumberland St, Toronto

An address of unmatched exclusivity, No. 155 Cumberland is an ultra-boutique Yorkville residence offering some of the largest and most luxurious condo homes in Toronto. Originally a mid-century office building, it was converted circa 2010 into an elite 11-storey condominium with only 15 suites—expansive half-floor and full-floor residences with private elevator entries. Suite sizes start around 2,200 sq ft and soar upwards, with 10–12 ft ceilings, bespoke Downsview/Scavolini kitchens, marble bathrooms, and extraordinary terraces (some with outdoor kitchens or fireplaces). Privacy and discretion define the experience: restricted-access elevators, 24-hour executive concierge, and valet.
