About Greenrock Real Estate Advisors

Greenrock is a third-generation family business with a proud tradition of giving back to the community.

In 1910, European immigrant Louis Green arrived in Toronto and began working as a bricklayer, with his sons joining him as the company grew. After WWII, Louis and his sons, including Greenrock’s founder, Al Green, developed the family business and built thousands of residential units across the GTA, including the city’s first planned community in Don Mills.

Al’s son, Barry Green, continues the family tradition today, serving as chairman of Greenrock. Greenrock manages some of the city’s most iconic rental properties in midtown and downtown Toronto. We are proud of our family history and our tradition of giving back to the community. Visit Greenrock IMPACT to learn more about how we are helping to create stronger, healthier and environmentally sustainable communities across Toronto.

Greenrock History

  • Humble Beginnings

    Louis Green business card
    European immigrant Louis Green arrived in Toronto and began working as a general contractor specializing in baker ovens and chimneys. His sons Al, Harold and Sam would later join him as the company grew.
  • Abraham “Al” Green

    Al Green Sculpture Studio & School

    The eldest of three brothers, Greenrock’s founder Al Green was born on February 1, 1925. Al Green would devote his professional life to providing affordable housing units to residents across the GTA.

    Now 15 years old, Al Green began working for his father’s business as a bricklayer in Toronto. By 1943, the family business had a net worth of $150 and a truck.

  • Greenwin Construction

    Greenwin Construction Company

    A post-war economic boom allowed for new investment in Toronto. Construction of the Yonge subway line from Union Station to Eglinton Avenue unlocked new areas for potential development.

    Over the next 30 years, Greenwin Construction Company would construct thousands of affordable houses, apartment units, and condominiums across the GTA.

  • Don Mills

    Wingreen Court

    In 1951, Greenwin Construction Company is awarded residential development rights to Don Mills. With the extension of the Yonge subway beyond Eglinton, and construction of the Don Valley Parkway in 1953, the once secluded Don Mills and Eglinton area was primed for new development. Greenwin was the first multi-unit developer to build in Don Mills, and would build over 1,000 residential units in Don Mills.

  • “Flying Form” Construction

    Flying Form Construction

    By the 1960s, Greenwin had developed a new innovative system for high-rise building called the “flying form.” The process involved hoisting preassembled forms (moulds) up one level at a time until the concrete was poured and settled. Once the concrete had settled, the form was removed and raised to the next level to repeat the process, greatly reducing the time for construction.

    The flying form technique revolutionized the high-rise construction industry and enabled Greenwin to build over 10,000 residential units across Toronto throughout the 60s and 70s.
