About Greenrock
Greenrock is a third-generation family real estate business with a proud tradition of supporting the community and seeking greater equity for all.
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.
Land Acknowledgement
Greenrock operates on the traditional territory of many nations including the Mississaugas of the Credit, Anishinabek (ah-nish-nah-bek) Nation, Haudenosaunee (ho-den-oh-show-nee) and Wendat (wen-dat) peoples.
This territory is protected by the Dish With One Spoon Wampum Belt Covenant, an agreement between the Haudenosaunee Confederacy, the Ojibwe, and allied nations to live in peace and take care of the land and creatures among us. The Mississaugas of the Credit were forced to give up their land by signing the Toronto Purchase (Treaty 13) in 1805.
As a real estate company that owns residential and commercial properties in Toronto, we feel grateful to provide safe and inclusive spaces for diverse members of our community to both live and work in harmony. At the same time, we feel a strong conviction – as settlers and their descendants—to acknowledge the colonial foundations upon which this city is built.
We vow to serve as proud allies to our Indigenous friends and community members who have and continue to call Turtle Island home for centuries.
Greenrock will remain forever grateful to live and work on this land.
Greenrock History
Humble Beginnings
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
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.
The Family Business
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
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
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
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.
