Course Certification

To receive a Level 1 tree marking certificate, you must successfully pass a written exam and 3 field exams. After gaining some field experience, you must select and pay a Level 2 tree marker to do an operational field audit on your marking

If you pass, your certificate is valid for 5 years. You must take a refresher course every 5 years to maintain a valid certificate.

Level 1 Tree Markers can get certificates for a single tree selection system and/or a shelterwood system. Level 1 Tree Markers that wish to become tree marking auditors require the Level 2 tree marking course.

Mandatory for Working on Crown Land

Courses are mandatory for all tree markers working on Crown land in Ontario. Several municipalities in Ontario also have By-Laws that require a woodlot to be marked by a certified Tree Marker.
