Suspicion of illegal activity in water supply and pipelines

The Corporation of Master Pipe Mechanics of Quebec (CMMTQ) wishes to inform the public that Laurie Boies and 9458-4414 Québec inc., doing business under the name Plombier Laval, are suspected of illegally practicing the profession of master pipe mechanic.

This company would also do business under the names Service Urgence, Plombier Urgence, Plombier Affordable, Plombier Monk, Plombier Saint-Laurent and Plombier Rive-Sud; and would carry out plumbing work without being a member of the CMMTQ, and therefore without holding the appropriate contractor’s licences.

Mode of operation

“Our research reveals that they operate in several regions of Quebec, such as Laval, Montérégie, Montreal, Lanaudière and the Laurentians. They use several names, phone numbers (514 307-3419, 450 987-3624, 514 532-0131, 514 535-0176, 514 319-0186 and 438 221-5390), websites ( and and Google Ads to contact potential customers,” CMMTQ said in its press release.

Measures taken

Concerned by the reported facts, the Corporation is currently taking action to prevent these individuals from practicing the trade of master pipe fitter.

Several malpractice claims have been filed in court against Laurie Boies and 9458-4414 Québec inc.

If found guilty, they face fines ranging from $5,000 to more than $75,000 per offense under the Master Pipefitters Act.

Consumers who wish to report these persons to the CMMTQ are invited to fill out the application form.

In addition, CMMTQ reminds that before entrusting the work of installation, repair, replacement or renewal of a water system, consumers must ensure that the person or company is a member of CMMTQ and holds the appropriate licenses.
