It also authorizes construction work on heating systems referred to in the first paragraph and carried out on the territory of a local municipality whose population does not exceed 5,000, unless it has a public sewer, or on an unorganized territory. 

Furthermore, this subclass authorizes construction work related to plumbing installations that are not the building’s installations and are located outside. 

Finally, it authorizes related construction work.

WATER PUMPS:

While authorized to assemble the pump inside the building, the contactor working on underground water pumping systems (2.3) cannot connect the pump to the building’s plumbing network, as this work requires a subclass 15.5 or 15.5.1 licence.

NO LICENCE IS REQUIRED FOR THE FOLLOWING:

  • pipe thawing work
