Can I replace a toilet myself without needing a permit in New Brunswick?

Yes, you can replace a toilet yourself in New Brunswick without a permit — this falls under basic fixture replacement that doesn't require plumbing licensing or permits from TIS (Technical Inspection Services).

What you can do as a homeowner: Remove the old toilet, install a new one in the same location using the existing water supply and drain connections, replace the wax ring, and reconnect everything. This is considered maintenance rather than new plumbing work. You'll need basic tools like an adjustable wrench, level, and possibly a hacksaw if you need to trim bolts.

When you DO need a licensed plumber and permits: If you're moving the toilet to a new location, installing additional fixtures, running new water lines, or modifying the drain system. Any rough plumbing work (behind walls or under floors) requires a licensed plumber and TIS permit. The same applies if you're adding a toilet where none existed before.

New Brunswick's plumbing regulations are strict — TIS licenses all plumbers and inspects plumbing systems. Unlike electrical work (which homeowners cannot do at all without proper licensing), basic fixture replacement is one area where DIY is permitted. However, if you run into complications like rotted subflooring, broken flanges, or discover the drain isn't properly vented, you'll need to call a licensed plumber.

Practical considerations for NB homes: Many older homes across the province have cast iron drain pipes that may be nearing end of life, especially in post-war bungalows from the 1950s-70s. If you notice rust, leaks, or the flange breaks during removal, that's when professional help becomes necessary. In rural areas on septic systems, ensure your new toilet is low-flow (6 litres or less) to reduce strain on your septic tank.

Your next step: Measure your current toilet's rough-in distance (from wall to center of drain bolts) before shopping — most are 12 inches, but some older NB homes have 10 or 14-inch rough-ins. Pick up a new wax ring and toilet bolts while you're at the hardware store, as these should always be replaced during installation.
