White Owl Family Office Group

White Owl Family Office Group was founded in 2015 by the McArthur and Carrick families. Capital originated from their ownership of McAsphalt Industries and Miller Paving, which Colas SA acquired in 2018 for approximately $910M CAD. The firm invests directly without external fund mandates. White Owl allocates across real estate, private equity, private credit, infrastructure, and fund-of-funds vehicles. Confirmed positions include board seats at Skyline Retail REIT and holdings in industrial, automotive, and environmental operating companies. The portfolio spans Canada and the United States with exposure to buyout, growth, and late-stage opportunities. Asset classes include mixed-use properties in Ontario, Manitoba, and Atlantic Canada plus an Oak Ridges Moraine development site in Richmond Hill, Ontario. The firm reports no disclosed AUM figure. It maintains two philanthropic vehiclesthe John & Margaret Carrick Family Foundation. White Owl belongs to Family Enterprise Canada and YPO. An additional office operates at 777 S Harbour Island Blvd, STE 400, Tampa, Florida. No operational events from the last 24 months appear in public records. White Owl differs from typical single-family offices through its direct operator background. The families previously ran road-building businesses and now apply hands-on management to portfolio companies, having acquired over 70 firms historically. This structure supports co-investments alongside external partners without quarterly return pressure.
