About
Gasfitters install and maintain the gas piping, appliances and equipment found in homes, businesses and industrial sites. This includes furnaces, water heaters, boilers, stoves and meters. Class A is the higher of the two gasfitter classes. It covers a wide range of work, including larger and more complex systems.
Each province and territory issues its own certificate of qualification. The Red Seal endorsement is added when you pass the interprovincial exam. It is recognised in every province and territory. This makes it easier to move and work anywhere in Canada without being retested.
How to get it

The exam
