If your certificate is still valid, you can take the H2S Alive Blended Renewal. It has two parts:
An online theory exam.
An in-person skills assessment at an Energy Safety Canada Authorized Training Provider.
Before you sign up, check these points:
Contact an Authorized Training Provider near you. Confirm that it offers the skills assessment.
You pay one fee for the online course and a separate fee for the assessment.
You have 90 days from registration to use the online course.
If you fail the assessment, you must register for the classroom course, and fees apply.
When you pass both the online exam and the skills assessment, you get a new certificate, valid for three years.
An expired certificate does not qualify for the blended renewal.
