Opening of MultiRés: A decarbonization program for multi-residential building owners

Montreal, June 11, 2025 – The Greater Montreal Climate Fund and Efficiency Capital have partnered to launch MultiRes and have announced that applications are now open for building owners to join the summer cohort of the MultiRes program. Targeting buildings with aging systems and high emissions, the program offers tailored retrofit plans that combine energy efficiency and electrification, helping owners navigate the technical and financial challenges of this transition.

MultiRés: lessons learned from field experience

After a successful two-year pilot phase, MultiRés has proven that no two buildings are alike. Field experience showed that pre-packaged solutions rarely fit: each property has unique characteristics — from system design to tenant profile — requiring a tailored approach. 

For example, the pilot revealed that electrifying a building can raise project costs by up to 25% compared to conventional equipment replacements. These upgrades often don’t generate enough energy savings to meet owners’ expected payback timelines, making them financially unfeasible without external support. That’s where MultiRés comes in.

“Building owners are under growing pressure not only to modernize outdated systems, but also to comply with new regulations banning fossil fuel heating,” says Chandra Ramadurai, CEO of Efficiency Capital. “They face particular challenges managing this shift. The MultiRés program will help absorb costs and deploy clean technology solutions proven to benefit both owners and tenants.”

A solution designed for building owners that will have a significant impact

The building sector accounts for 26% of GHG emissions in the CMM — a major challenge for the region’s climate ambitions. By supporting large-scale retrofits, the MultiRés program offers a practical path to significantly lower emissions while improving building performance. Owners who join the program can reduce operating costs, enhance property value, and contribute directly to Greater Montreal’s transition toward carbon neutrality.

“Building decarbonization is one of our biggest climate challenges — but also one of our biggest opportunities,” says Vincent Moreau, CEO of the Greater Montreal Climate Fund. “With MultiRés, we’re giving owners the tools to act, accelerating the transition to a low-carbon Greater Montreal, and helping the region meet its 2040 decarbonization targets.”

Apply now

Owners may qualify their buildings here. Individual buildings smaller than 6 units are not eligible unless they are combined with several buildings under the same owner. The building must be located in a Greater Montreal area including Kanesatake or Kahnawake territories.
