The Dorchester Corporation owns, develops, and manages real estate investment properties in Canada and the United States.

Since our incorporation in 1966, we have been active in all aspects of the real estate industry including greenfield development, property management, asset management and investment banking.

Over the last few years, we have re-focused the company on value-added property investment and development. We are currently undertaking the complete re-development of a 40-story landmark office building in downtown Chicago—The Jewelers Building at 35 East Wacker Drive.

The company is also an active participant in the energy sector and, with partners, is owner and developer of oil and gas producing properties in Canada and the United States.

The Dorchester Corporation operates out of offices in Toronto and Montreal in Canada, and out of Chicago in the U.S.


Over its 40 year history, The Dorchester Corporation has been active in all aspects of the real estate industry. Significant events in the company’s history include:

Investment Banking

The Company merged with Marcil Group and grew Marcil Trust into Canada’s leading real estate investment banker. Marcil Trust was sold into partnership with Royal Bank of Canada (RBC) in 1990 and the remaining minority interest was sold to RBC in 1996.

Asset Management

The Company acted as external manager of the Canadian Real Estate Investment Trust from 1996 when the Trust had $C80 million in assets, until 2001 when management was internalized and assets had grown to $1.0 billion. Former principals, managers and employees of Dorchester continue to run the Trust and Dorchester remains a significant unit holder.


The Jewelers Building is a 40-story landmark office building located in downtown Chicago on the corner of East Wacker Drive and Wabash Avenue, facing the Chicago River.

Known as The Jewelers Building, 35 East Wacker Drive was originally designed and built in the 1920’s as a high-tech office tower for jewelers. The lower 23 floors were serviced by automobile elevators that, for security reasons, transported the tenant, their jewels, and car directly up to the office floor. This machinery proved less useful over time, and the elevator shafts were subsequently filled in.

At the time of its construction, The Jewelers Building was the tallest building west of New York City. Its silhouette is distinctive on the Chicago skyline. It has a “wedding cake” shape with water towers visible at the four corners of the first set back (part of the original fire suppression system—now decommissioned). The top of the Building is a large dome which originally housed a restaurant said to have been an Al Capone hangout during Prohibition. The Building is a designated Chicago landmark.

Recently, The Dorchester Corporation initiated a multi-year, multi-million dollar renovation program to bring the property up to contemporary Class A standards. The interior of the building is being entirely re-built on a floor-by-floor basis as tenants vacate, with only the building structure and the restored historic facade remaining in place.

The Building core has been reconfigured around a new centrally located services shaft—creating modern floor plates ideally suited to mid-sized office users. New “best-in-class” electrical, mechanical, elevator, plumbing and life safety systems have been installed. The storefronts, lobby, and elevator cabs have been meticulously restored. The Building now offers modern functionality in a prestige heritage space.

The property re-development has received awards including a top award from the Chicago chapter of the American Institute of Architects (the “Interior Architecture Award Citation of Merit” for Excellence in Architecture 2006) and the “2006 Chicago Landmark Award for Preservation Excellence—Exterior and Interior Rehabilitation” from the City of Chicago.
