Building Design and Construction

LEED® Canada NC 1.0

Certification support for this rating system closed June 21, 2017. New projects must register under LEED v4.

The LEED® Canada NC rating system applies to new construction and major renovations of commercial and institutional buildings, i.e., buildings regulated by Part 3 of the National Building Code. It also applies to retail, mid- and high-rise multi-unit residential buildings (MURBs), public assembly buildings, manufacturing plants, and other types of buildings.

Applicants with space that is not fitted out at the time of certification (e.g., intended for future lease) may wish to consider LEED Canada for Core & Shell. Applicants with 50% or less of the building fit-up for certification may use the Application Guide for Core and Shell Buildings and Leased Tenant Spaces as noted below.
