Septic permits in Ontario

1 min readUpdated Sep 26, 2026

In Ontario, a new or replacement septic system needs a permit before the work starts.

We handle the whole permit process

From completing the paperwork accurately to submitting it promptly, so you do not have to.

Licensed to do the work

We are fully licensed by Ontario's Ministry of Municipal Affairs and Housing (MMAH) and are members of the Ontario Onsite Wastewater Association (OOWA).

Part of a new build?

Builders bring us in for the septic system along with the demolition, excavation, concrete floors, drainage and grading, so one company handles the site work.
