The Canadian headquarters of Google in Toronto has been put on the market. The tech giant has been the sole office tenant at the 18-storey building at 65 King St. E. for the past five years.

Located on the western side of Church Street, kitty corner from The Cathedral Church of St. James and St. James Par, the office building was completed in 2021.

It was developed and is co-owned by Toronto-based developer Carttera, Manitoba pension fund Civil Service Superannuation Board (CSSB) and Ontario pension funds OPTrust and the Investment Management Corporation of Ontario (IMCO).

Prior to completion, the co-owners announced that Google had signed a long-term lease for all 18 floors of the building. 

The class-AA office building was designed by WZMH Architects alongside Arcadis (formerly IBI Group) and was constructed by PCL Construction, winning the NAIOP Real Estate Excellence Award for Office Development of the Year in 2023.

The downtown Toronto office market

The listing coincides with signs of renewed activity in the downtown Toronto office market. In its Q1 Greater Toronto office market report, Avison Young noted investment activity seems to be following an uptick in leasing.

"After a lengthy lull in major institutional-grade building sales, some transactions closed in late 2025, and other large assets – both downtown and in the suburbs – are known to be coming to market soon," the report said. "As the leasing market recovers, sellers may
feel more comfortable with asset pricing, while the sector’s appeal for buyers increases."

Vacancy in downtown Toronto offices fell during the quarter to 13.1 per cent, the report said, adding: "leased area across the downtown market increased by more than 1.6 million sf during the quarter as big gains in class A buildings more than offset losses in class B and flat results for Trophy (where available spaces are scarce) and class C buildings."

Notable office sales over the past six months include 70 York St., which KingSett sold for $134.6 million in late 2025 and 141 Adelaide St. W., which was acquired by Spear Street Capital for $95.25 million.

Last month, BGO bought the office building at 95 Wellington St. W. from Cadillac Fairview for $198 million and, as RENX reported earlier this week, the former two-building CPP headquarters at 1 Queen St. E. and 20 Richmond St. E. was sold to Infrastructure Ontario for $145 million in May.

65 King Street East

The property was listed by Peter D. Senst, Jaysen Smalley and Kai Tai Li from CBRE Toronto’s National Investment Team on an unpriced basis, according to a sales brochure obtained by RENX.

“The Property is being offered free and clear of financing allowing investors to capitalize on attractive debt terms driven by Google’s strong credit rating,” CBRE notes in the sales brochure.

The floor plates range from 15,700 sq. ft. to 29,100 sq. ft., the building includes 18,152 sq. ft. of terrace space that spans eight floors, and it is serviced by an on-site underground parkade with 209 vehicle stalls and 196 bicycle stalls. The parkade is owned by a third-party operator, according to CBRE.

The building is certified LEED Gold and WiredScore Platinum.

Google invested over $200M in customizing, adding amenities

65 King St. E. houses 405,276 sq. ft. of net rentable area, there is some ground-level retail space in addition to the office space.

Google’s lease was for 15 years and there is over 10 years remaining. CBRE notes that since Google took occupancy of the building, they have invested more than $200 million towards customizing and improving their space with amenities such as cafeterias, internal staircases and a two-storey auditorium.

CBRE did not disclose the net rent Google is paying, but said that the in-place net rent represents a 45 per cent to 50 per cent discount on replacement cost.

Outside of Toronto, Google only has two other offices in Canada, according to its corporate website. Those are located at 425 Viger Ave. W. — known as the Read Building — in Montreal and 51 Breithaupt St. — Phase Three of Breithaupt Block — in Kitchener, both of which are owned by Allied Properties REIT.
