Subclass 1.3 limited

On June 25, 2008, following the coming into force of the Regulation respecting the professional qualification of contractors and owner-buildersThis link open an external website of the Régie du bâtiment du Québec in a new window., the Régie du bâtiment du Québec (RBQ) sent all contractors who held licence subclass 1.2 (Contractor – Small buildings), but did not have licence subclass 1.3 (Contractor – All buildings), a new licence containing the addition of subclass 1.3 limited – Contractor – All buildings. This measure was taken to preserve the rights of small building contractors.

This subclass is "limited" in that it includes only the work authorized by subclass(es) that contractors held prior to June 25, 2008 (former subcategories 4041, 4043, 4047, 4050.1 and 4050.2). Please refer to the Concordance Table in Schedule IV of the List of Licence Subclasses.
