I'm a Day late.. But Happy Earth Day!!

Yesterday our President, Dr. Mark Charbonneau and our Vice-President Sylvia Rennie attended the unveiling of the beautiful bronze statue sponsored by Testmark. Beautifuly crafted by local Sudbury artist Tyler Fauvelle., this tribute to the late Dr. Jane Goodall is the first in a series of civic statues coordinated by Laurentian University to remind us of Dr. Goodall's environmental legacy!

Good Morning Everyone! To our valued Clients and Staff - Thank you for your patience while we "Dig out" here in Sudbury! Due to the significant weather event - we are facing a few delays due to staffing constraints with some of our folks still stuck behind massive snow walls. This may cause a 1-3 day delay on some reports being issued. We apologize for any inconvenience this may pose, but do sincerely thank you for your understanding! Another day or two and hopefully the city will back to running normally! Stay safe out there, bend at the knees and "Just keep digging"

03/16/2026

March 16, 2026: Due to the significant weather events in Northern Ontario, for the safety of our Staff and Clients - our Garson, Timmins and Kirkland Lake Testmark lab locations will be CLOSED today. Please note, that these closures do also affect Customer Service for Thompson and Thunder Bay sites as well.

Have a great day, and please stay safe and warm.
