2017 Winner Canada's Top 100 Small and Medium Employers

Hy-Mark is a full service mechanical company delivering best-in-class workmanship and offering ongoing support to our valued customers. From commercial and residential builds, to renovations and service – we take your projects from conception to completion and maintain your equipment for years to come. Over its 13 years in the industry Hy-Mark’s name has become synonymous with Innovation, Service, and Values.


Hy-Mark is an industry leader when it comes to innovation in sustainable building methods.  We are proud to have worked on some of the first homes in Canada to be “Net Zero,” a qualification signifying a home produces the same amount of energy it consumes. Hy-Mark has also completed seven large residential communities since 2012 built to Energy Star efficiency guidelines.

How do we do it? By choosing better, smarter building materials and top of the line equipment, and by having an unwavering commitment to excellent quality of work.  Most importantly, our team strives for continuous improvement every day in all that we do.


At Hy-Mark, everything we do starts with the customer.  We understand that no two customers’ needs are exactly the same.  That’s why we go above and beyond to ensure every customer receives the best value from their experience with our company.


We live by our Core Values.  We believe Hy-Mark is the sum of its individual employee actions.  That’s why every one of our team members models these Core Values in life and work.  The sum of those actions?  A company that is truly guided by its principles.

When you work with Hy-Mark, you work with a company committed to doing what is right.
