About Us

Our history of innovative construction tempered with tradition distinguishes us a multi-trade contractor and fabricator of choice.

Our Story

The Nicholls name from which WSN Construction derives has been in the Canadian construction market for over 40 years. Since our establishment, we have experienced steady growth with a solid base of repeat customers.

In 1975, Bill Nicholls and Dave Radtke founded the construction group of Nicholls-Radtke. Throughout his time at Nicholls-Radtke, Bill Nicholls developed strong relationships, insightful experiences, and a knowledge of construction that formed an integral part of who he was. Bill was a driven individual who was instrumental to all the successful undertakings the group achieved.

With change in the wind for Nicholls-Radtke, Bill made the difficult decision to move in a bright new direction where he could bring his skill set to bear in new markets and challenges. Following a brief hiatus from the industry, Bill made the historical decision to found W.S. Nicholls Construction Inc. in 1996.

Since the inception of W.S. Nicholls, we have been a strong presence in the Ontario industrial construction market, providing elite services to a number of repeat partners. From those successes, W.S. Nicholls increased its national footprint. In 2000, operations expanded into Western Canada with W.S. Nicholls Western Construction Ltd., located in Delta, British Columbia.

Continued growth and success led to the 2010 acquisition of W.S. Nicholls by the Link-Line Group of Companies. When Link-Line was later acquired by Centuri Group, Inc. in 2014, W.S. Nicholls also became a Centuri company.

In 2020, the W.S. Nicholls brand evolved to WSN Construction. The new look represents the advancements within the organization, while paying tribute to the best parts of our heritage. Our history, combined with our forward-looking spirit, continues to be the backbone of our successes and the differentiating factor between us and our competitors.
