Hi, My name is Chris Sawyer.

Here are a few tidbits about me:

I am an expert in Environmental Engineering, Mould Certification, and Indoor Air Quality, and I am certified by the IICRC for Water Damage and Fire and Smoke Restoration.

Over the years, I’ve had several opportunities to work in different and diverse centres across Canada, as well as in other countries around the world. A few highlights include:

  • Fort McMurry Fires in 2019
  • Mould Consultant on a Government tender in Nunavut
  • Mould Consultant in Puerto Rico after the largest loss on the island


Through my many consulting opportunities, and my 9 years of experience in the industry, I’ve been fortunate enough to meet so many other amazing industry experts. I love to ask questions and I’m a sponge for knowledge. Everything new that I’ve learned, from some of the best in the industry, I’ve applied and implemented at OMS.

OMS is a full-service company, which means you don’t have to worry about contacting multiple companies to complete a job. We remediate from the basement right up to the attic and take care of improving your indoor air quality as well.


OMS is 100% Canadian-owned and operated, and is a family labour of love.

It’s always safety first here at OMS and ensuring our policies, business procedures, and training procedures are all at the highest level, is what sets us apart from the competition.

The rigorous training we provide to our team of professionals, together with the use of the best tools, the best products on the market, and the best industry practices, makes us the best in Ontario.

Over the years, thousands of families, building inspectors, and real estate agents have trusted us with their homes, their health, and the success of their businesses.
