Démex was founded in 1992 and has grown to be one of Canada’s top industry leaders in demolition, deconstruction and recycling.

Démex leaders are proud of the reputation the company built while working under the Tremblay family, who were demolition contractors for several years. Our specialists work together, using their vast experience to carry out each stage of the deconstruction project. Being a demolition company means more than dismantling buildings; it means building the future and helping drive customer success. As demolition contractors, the key is to support our customers’ ambitions and make their success ours too.

The success Démex has had with its myriad projects proves that there is no issue or project that this team of deconstruction experts can’t handle. Démex boasts an impressive portfolio and through major investments in research and development, we can tackle challenges that others find impossible to take on.
