What is a “sustainable building”? It is a building that has energy efficient equipment, updated plumbing, quality air systems and a method of monitoring and controlling its usage. A sustainable building keeps its occupants healthy, it helps to keep the environment clean, and a sustainable building saves money.

Whether it’s a new or old building, MJS can make sustainability a reality.

Through creating valued partnerships with our clients, our vendors, our sub-trades, our employees and leading industry experts we are able to offer you an exceptional experience.

Our vision allows us to be more cost-effective, increase productivity, provide value-added services, and progress towards higher sustainability in buildings.

COR CertifiedAt MJS, we value the importance of safety in the workplace. The health and wellness of our employees is a top priority. We have developed a comprehensive safety program that focuses on making safety clear and concise vs. a program that is full of jargon and difficult to follow. This will allow for ease of use and understanding of our best practices and procedures, ensuring they are practiced daily on our sites.

We are COR certified.

We promote reporting all near misses and incidents. Rather than covering up potential mistakes, we believe in learning from the experiences. Through reporting, other employees can learn more about common workplace hazards and can avoid them in the future through our root-cause analysis.

Tradition of Giving Back

MJS Mechanical Contracting Corporate Culture of Giving Back

The team at MJS Mechanical understands the importance of giving back. Corporate Social Responsibility (CSR) is an integral part of doing business.

We are proud to support both local and international causes. In developed countries like Canada, we are so lucky to have access to fresh, clean drinking water almost anywhere you go. Unfortunately, many places in the world do not. As a mechanical contractor, our focus is on helping those who suffer from water scarcity, non-potable water, and out-dated plumbing.
