About Us

Mattawa Industrial Services (‘The Moose Herd’) is an industrial maintenance service contractor focused on down-stream oil, gas, and petrochemical markets in Canada and the United States.

Mattawa is made up of Mattawa Industrial Services, Inc. and Mattawa Industrial Services (USA), Inc., both wholly owned subsidiaries of Envirosystems Incorporated, which is headquartered in Dartmouth, Nova Scotia, Canada.

We are ‘The Moose Herd’, a relatively new company with familiar faces. Many of the personnel that make up ‘The Moose Herd’ have been in the industry for more than 30 years.

We specialize in three primary service areas – catalyst changeout (including inert entry), industrial services, and water management services.

We have old fashioned values and some of the best and most experienced professionals in the business. Our management team has well over 100 years of experience delivering successful catalyst handling and industrial services projects in refineries, chemical, and petrochemical plants across North America.

Central to everything we do is the health and safety of our employees. All of our employees are part of our family and our goal is zero incidents – as we say, “everyone home safe, every day”.
