Frequently asked questions

How is Western Securities Investment structured—as a single family office or an operating real estate company?

Western Securities functions as an owner-operator rather than a traditional family office. The firm directly owns, manages, and develops its real estate holdings across Canada and the United States, with in-house property management and leasing capabilities. It does not operate as a multi-family office, does not accept outside capital, and has not created separate fund vehicles or investment management subsidiaries for third-party investors.

Does Western Securities Investment participate only in direct real estate, or does it also make fund commitments?

The firm's investment model is overwhelmingly oriented toward direct real estate ownership and development. There is no public record of Western Securities committing capital to external private equity funds, venture funds, or real estate investment trusts as a limited partner. The portfolio is characterized by wholly- or majority-owned physical assets, including retail centers, residential towers, mixed-use developments, and agricultural land.

Which geographies and property types does Western Securities Investment target?

Western Securities concentrates its portfolio in Calgary, Alberta—where it holds North Hill Mall, The Underwood, Stadium Shopping Centre, First Street Market, Lynbrooke, and Renaissance Towers—and in the U.S. Sun Belt through its Western Securities USA arm, which owns mixed-use assets in Dallas, Texas, and Phoenix, Arizona. The firm also maintains a portfolio of farm and ranch lands across North America. Property types span retail, multifamily residential, office, and mixed-use.

Where does the underlying O'Connor family wealth come from?

The family wealth originated with John J. O'Connor, who founded a securities brokerage in 1932. Over subsequent decades, the family redirected its capital into direct real estate investment, beginning in Calgary and later expanding into the United States. The wealth is now embedded in the property portfolio itself, with no publicly disclosed operating business outside of real estate that generates the family's capital base.
