Important: Ontario has strict limitations on which quality control programs are acceptable for piping. See the piping QC section below.

These Ontario piping flowcharts are copied directly from TSSA document SB00-7:

Flowchart of Piping process in Ontario Part 1

Flowchart of Piping process in Ontario Part 2

Flowchart of Piping process in Ontario Part 3

These flowcharts do not include the “TSSA requirements for medical gas piping. These charts have been modified with Code Adoption Document and refrigeration system comments by PVEng.
