How to Become a Licensed Sewage System Installer in Ontario

How to Become a Licensed Sewage System Installer in Ontario

Onsite Sewage System installers in Ontario are regulated by the Ministry of Municipal Affairs and Housing (MMAH). Installers must take several steps to be recognized as a registered practitioner in our province. The following information outlines four steps to becoming a registered (licensed) sewage system installer.

Step 1: Obtain Your Building Code Identification Number (BCIN)

To register for your BCIN which is a personal identification number, visit the MMAH website. You will be redirected to the QuARTS system to complete the registration. QuARTS is a public registry of all Ontario Building Code (OBC) practitioners and BCIN holders. By obtaining your BCIN you will be identified on the QuARTS system by MMAH as such.

Step 2: Prepare for the OBC Part 8 Licensing Exam

There are many  courses available to prepare you to challenge the exam. Part 8 preparation courses are not a mandatory step in the process; however, it is highly recommended.  These courses generally run for 5 days and will address the fundamentals of sewage system functionality, basic design considerations and Division B, Part 8 of the OBC.  An example of the syllabus for the exam can be found on the Government of Ontario’s website. There are a number of course providers who deliver both on-line and in-person classes. OOWA is proud to partner with some of these course providers and maintains a list of available courses in our Events Calendar as well as our monthly On-Track Bulletin – one of many OOWA Membership benefits.

Step 3: Book Your Exam Date and Location

Humber College administers all Ontario Building Code exams. Visit their website to see an exam schedule and register for your exam. Exams are conducted on-line and can be written at home, the office, or at a nearby college. Be sure your computer has the required audio and video capabilities to complete the exam. The QuARTS system will send you an email notification when your exam results are available.

Step 4: Register with MMAH and Pay Registration Fees

To register with MMAH, you must create a One-key account. ONe-key is a unique electronic credential that allows you to communicate securely with online Government services. One-key is used for other services and registrations in Ontario so be sure that you do not already have an account. The following fees must be paid in ONe-key for your initial registration and to renew your license every year.

On-site Sewage System Installers ( of Div. C; 2023 rates):

  • Initial registration or reinstatement – $128.00
  • Annual registration (license) renewal – $128.00

Allow a few days for processing after you register before checking the status.

Suggested Step 5: Join the Industry Association

The Ontario Onsite Wastewater Association advocates to the Government on behalf of professionals in the onsite wastewater industry and represents our members with our organizational partners.  Because OOWA sits at tables where individuals cannot, there is power in our numbers.  As our membership grows, our ability to improve the industry for our members increases.  Show your clients that you are an engaged and current professional by becoming a member of the Association. Set yourself apart from your competitors.  Join us.
