Along with an Application for a Permit to Construct, municipalities within Ontario may require a Mechanical Ventilation Design Summary (MVDS) and/or Record form to be completed by a Certified Design Firm. The one page form is intended to ensure that the Ontario Building Code’s 2012 minimum ventilation requirements are being achieved. One MVDS form is required for each dwelling (apartment, house, semi, civic address).

Requesting an MVDS form(s) is easy!


To start please fill out the form below. It is ideal if you have one mechanical ventilation specification going into one or multiple units/addresses. Once the form is filled in for the first address (or unit) you may enter additional addresses (or units) to which this same specification applies. Our forms come with a full warranty; should the form require a revision at a later date this update is included in the original fee.

$100.00 each + $50.00 per additional form (CAD)

Residential Dwellings Only
