our history

 “If you always do what you always did, you’ll always get what you’ve always got.” 

– Henry Ford 


As a newly emerging leader in the Canadian construction industry, Lean Construction Services (LCS) roots go back over 35 years to when we began doing business as Ross & Anglin Ontario LTD in Toronto, ON.  As a third generation family owned business, we have a history of tradition, quality, integrity, and dependability. After 35 years in the construction industry, we have combined our history, modern-day practices and new technologies to thrive into the 21st century. We are happy to share where we started and where we've come so enjoy our full history below!
