- Permits for many plumbing alterations are issued by the City of Oshawa building department.
- Plumbing is a compulsory trade in Ontario — work for hire must be done by a certified plumber or supervised apprentice.
- Gas appliances such as gas water heaters require appropriately certified gas technicians.
