Section 17 of The Winnipeg Building By-law No. 4555/87 has been amended to identify an additional Mechanical Contractor’s Licence – M-Prime.  This designation acknowledges those mechanical contractors who oversee the mechanical scope of work on a project but subcontract that work to licenced M1 or M2 contractors rather than have licenced contractors on staff.  The new designation enables such a person or company to obtain the necessary M1 or M2 permits and be the prime contact for the Mechanical Inspections Branch.

The Building by-law includes the following definition:

A Prime Mechanical Contractor means an individual, partnership, firm, corporation or government department contracted to undertake mechanical work that may or may not hold a valid Mechanical Contractor’s Licence “M1” or Mechanical Contractor’s Licence “M2” issued in accordance with this By-law.


What this means is that someone who isn’t a licensed M1 or M2 Mechanical Contractor may acquire an M-Prime Mechanical Contractor’s Licence, and be issued an M1 or M2 Mechanical Permit under the condition that a licenced M1 or M2 contractor – as applicable – is identified as performing the work.  M1 and M2 permit applications made by M-Prime contractors will not be processed if a licenced M1 or M2 contractor is not identified.


When a permit application is made by a licenced M-Prime contractor, the licenced M1 and M2 contractor they identify on that application will receive an email indicating they’ve been identified on a permit application.  The email will include instructions and contact information for what steps to take if they have been incorrectly identified on a project.  M-Prime contractors should be aware that if they incorrectly identify a licenced M1 or M2 contractor on a permit application form, the permit or application will be immediately cancelled with a non-refundable administration fee being with-held, and re-application necessary, before the permit will proceed.


Mechanical Permit application forms have been revised to accommodate these changes.  There are no changes to types of mechanical permit applications.  The M-Prime licence simply allows a wider range of entities to obtain a mechanical M1 or M2 permit.


A separate M-Prime Mechanical Contractor’s Licence application form has been created.  Like other mechanical contractor licences, no exam is required.  The M-Prime licence is available in one-year and three-year terms with pricing similar to that for existing licensed contractors – see Page 30 of the Planning, Development, and Building Fees and Charges.  All M-Prime contractors will be identified as such and included on the published list of licensed mechanical contractors on the City of Winnipeg website.


To apply for an M-Prime Contractor Licence email contractorlicence@winnipeg.ca or visit Contractor Licenceing at Unit 18 – 30 Fort St.  Also, see the Contractor Licencing area of our new Mechanical and Plumbing info Centre webpage.
