Choosing a septic system for your Ontario property feels like a high-stakes decision, because it is. You're not just installing a utility; you're investing in your property's long-term health, value, and environmental footprint. With complex regulations from the Ontario Building Code (OBC), varying site conditions, and a dizzying array of system types, it's easy to feel overwhelmed.

Selling your cottage, refinancing your rural property, or just opening your mailbox to find an inspection notice from the municipality - these are the moments when Ontario property owners suddenly realize they need to know exactly when septic inspections become mandatory. The rules aren't the same everywhere, and what applies to your neighbour's property might not apply to yours.
