“If it’s worth doing, it’s worth doing right.”
Oscar Ladouceur

Oscar Ladouceur accepted his first contract and opened up Oscar Ladouceur & Son – a plumbing and sheet metal company.


The business grew and moved from his basement to a new 1,500 sq. ft. building at 337 7th Street East.


Fabricated completely out of sheet metal, Oscar fabricated “Oscar the Tinman,” the company’s trademark, as well as a large lightbulb for the Canadian Cotton Mills 50th anniversary.


Oscar’s son, Roger, joined the business. Starting with his plumbing apprenticeship and completing numerous trade courses to eventually becoming President of the company until retiring happily.


The company transformed from residential to commercial & industrial. Having outgrown their existing facility, they bought land and proceeded to build a new 4,000 sq ft. shop at 355 Balmoral Avenue. 


  • Designed and installed the mechanical requirements for a large majority of the industries being located in the new Industrial Park. 
  • Due to the increased work load, the sheet metal shop was expanded to 6,500 sq. ft. 


Michael Ladouceur, grandson of the founder, joined the company as a plumbing apprentice and became a certified High Pressure Welder. Today, Michael is the President of the company.


At the time, Michael was managing the industrial projects when he realized the potential of work that could come from opening a metal fabrication facility. As a result, Roger & Michael opened up Olsonfab Metal Fabrication.

Oscar Ladouceur & Son awarded Industry of the Year by the Cornwall & Area Chambers of Commerce.


Shelbie Ladouceur, daughter of Michael and granddaughter of Roger, joined the company after completing her post-secondary education in Business. She now acts as the Assistant to the President.


To accommodate the companies’ growth, an additional shop facility was acquired at 57,000 sq. ft. at 235 Saunders Drive, in Cornwall ON.
