Recent headlines have spotlighted Build Canada Homes, a new federal agency tasked with accelerating affordable housing construction at scale. The agency aims to use public land, flexible financing, and private partnerships to deliver affordable homes faster and at scale—a welcome initiative in these trying times for home buyers.

But speed without standards is a recipe for failure. Unless today’s homes are built to be durable, healthy, and energy-efficient, we’re setting Canada up for tomorrow’s housing crisis.

Net Zero is the Law, So Why Isn’t It the Standard?

Canada is among over 120 countries worldwide that have formally committed to achieving net-zero greenhouse gas emissions by 2050. At home, this commitment is enshrined in law through the 2021 Canadian Net-Zero Emissions Accountability Act, which requires governments to set targets, report on progress, and ensure accountability.

Net-zero is not an optional ambition, it is legislated. Yet Build Canada Homes, as currently framed, makes no guarantee that the hundreds of thousands of homes built with public money will even come close to that standard.

How can Canada credibly claim to be on a net-zero path while approving mass housing developments that will require costly retrofits or even full replacements before 2050? If these homes are built near minimum code, the contradiction is glaring.

The Energy Burden of Code Homes

A true net-zero home would use 50 to 90% less energy than a home built to code. Its smaller heating and cooling systems mean lower energy bills for residents and far less strain on Canada’s energy grid.

By contrast, building inefficient homes today locks families into decades of higher energy costs. It also locks Canada into higher fossil fuel use just when we are supposed to be phasing it out.

The logic is simple: we cannot reach net-zero as a nation while building homes that consume two, three, or even four times more energy than necessary. Each near-code home built today is another anchor dragging us away from our own legislated climate targets.

Affordability Is More Than the Sticker Price

Policy-makers often talk about affordability strictly in terms of purchase price. But real affordability includes operating costs.

A house that costs less to build but thousands more to heat and cool every year is not affordable. Canadians deserve homes that provide long-term financial relief, not decades of inflated energy bills. True affordability requires efficiency, and efficiency requires higher standards than code.

The Solution: Make Net Zero the Baseline

Canada’s commitment to net-zero by 2050 must now shape the way we build. Net-zero should be the baseline standard for every new publicly funded home, not an optional premium. 

Getting there isn’t about reinventing the wheel—it’s about applying proven practices.

• Airtight construction with blower-door testing;
• Proper insulation and thermal-bridge free detailing
• Heat recovery ventilation for fresh, healthy air
• High-performance windows and doors that hold not leak energy
• Integration of renewable energy where possible

Design frameworks like Passive House have already demonstrated that these approaches can deliver durable, healthy, low-energy homes affordably at scale. But the specific label matters less than the outcome: guaranteed affordable, net-zero performance.

Build Canada Homes is a once-in-a-generation chance to get this right. The choice is clear: use public money to build homes that are affordable, healthy, and net-zero from the start or knowingly construct a new housing crisis for tomorrow.
