Western Securities Investment
Ryan and Sean O'Connor co-lead Western Securities Investment, the 1932-founded family real estate firm with holdings from Calgary to Dallas and Phoenix.
Western Securities Investment
Western Securities Investment traces its origin to 1932, when John J. O'Connor established a securities brokerage that would evolve into a multi-generational real estate operating company. The firm is now chaired by John O'Connor, with fourth-generation brothers Ryan and Sean O'Connor serving as Co-Presidents, and Michael J. O'Connor as President. The O'Connor family has held and operated Calgary commercial and residential property continuously for over nine decades, making them a quiet but durable fixture in the Canadian private-property landscape. The firm's investment posture is concentrated in direct real estate ownership and development. Its portfolio spans retail, office, residential, and mixed-use assets. In Calgary, its holdings include North Hill Mall, a longstanding community shopping center; Stadium Shopping Centre; The Underwood, a luxury residential tower on 1st Street S.W.; and First Street Market, a food-hall concept. The firm also owns Lynbrooke, a residential rental property, and Renaissance Towers, a mixed-use project adjacent to North Hill Mall. Through its Western Securities USA arm, the O'Connors have extended their reach into Dallas, Texas, and Phoenix, Arizona, where they hold mixed-use portfolios. The firm also controls farm and ranch lands in North America, providing a tangible-asset underpinning to the portfolio. Executive leadership reflects a gradual generational transition. Ryan O'Connor is the public-facing CEO and Co-President, regularly representing the firm at Calgary real estate forums, while Sean O'Connor serves as Co-President with a focus on stewarding the family legacy. Mike Brescia holds the Chief Operating Officer role, providing operational continuity alongside the family principals. The firm maintains membership in industry bodies such as the Urban Land Institute, where it contributes to Emerging Trends reports, and the Calgary Residential Rental Association. The O'Connors have deliberately avoided external capital or fund structures, preserving full control across their assets. Western Securities Investment's structural differentiator is its nine-decade operating history within a single family, a rarity in North American real estate. Unlike most family offices that diversify across asset classes, the O'Connors remain almost exclusively committed to direct property, functioning more as an owner-operator than a passive allocator. Their combination of retail, residential, and agricultural land holdings, paired with a multi-city North American footprint, reflects a patient capital philosophy that prioritizes asset control and intergenerational continuity over rapid scaling or third-party fundraising.

Frequently asked questions
Who runs investment decisions at Western Securities Investment?
Investment and operational decisions are led by the O'Connor family's fourth generation: Co-Presidents Ryan O'Connor and Sean O'Connor, alongside President Michael J. O'Connor. Mike Brescia serves as Chief Operating Officer, providing non-family executive oversight. The firm's governance structure indicates that major capital allocations and property acquisitions remain directly under family control rather than delegated to an external investment committee.
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.
How does the O'Connor family handle succession and governance?
The firm has progressed through at least four generations of family leadership. John O'Connor serves as Chairman, while sons Michael J. O'Connor (President), Ryan O'Connor (CEO and Co-President), and Sean O'Connor (Co-President) occupy active executive roles. Daughter Kelly O'Connor is also identified as part of the fourth-generation leadership group. The presence of a non-family COO, Mike Brescia, suggests a hybrid governance model that blends family authority with professional operational management.
Does Western Securities Investment maintain any philanthropic structures or foundations?
There is no publicly disclosed philanthropic foundation or donor-advised fund directly linked to Western Securities Investment or the O'Connor family. The firm's communications and public records emphasize its real estate operations, tenant relationships, and industry participation rather than a visible charitable vehicle. Any family giving likely occurs privately outside the Western Securities entity.
