$17.5M Million Acre Challenge pays Ontario farmers to go regenerative

A $17.5 million program is paying Ontario farmers per acre, over three years, to adopt regenerative practices — with half the money arriving before implementation each year, not after.

The Million Acre Challenge, run by the Canadian Alliance for Net-Zero Agri-food (CANZA), launched in 2025. Phase one enrolled 15,105 acres across 32 farmers and 175 fields in southwestern Ontario. Every participating farm adopted at least one new regenerative practice, whether cover crops, nutrient management changes or other interventions.

Who is funding it, and why it matters?

Two donations from the Weston family totalling $17.5 million underwrite the whole program. The design target is simple: remove the cash-flow barrier that typically stops farmers trialling sustainable practices. Similar programs often demand upfront investment, which CANZA avoids by paying 50 per cent of the annual rate before the practice goes in the ground.

For a farmer weighing a switch to cover crops or revised nitrogen strategy, that structure changes the risk maths. The remaining 50 per cent follows implementation.

What did phase one deliver on the ground?

Buck Ross, 70, of Ross Enterprises in Moorefield, County of Wellington, is one convert. A fourth-generation farmer raising chickens for eggs, turkey and cash crops on Sideroad 12, Ross used the challenge to trial nitrogen stabilization and management on roughly 278 acres of corn, aiming to lift yield and overall production. He also applied replenished fertilizer on the same ground.

The result was unambiguous. "We got a wonderful crop, the best we've ever had," Ross said.

His motivation runs longer than one harvest. Ross said he signed up because he's been thinking about the world his six grandchildren will grow up in. He called the program a "really good thing" for local farmers that supports and extends ecological work many were already doing quietly.

"I think it's really good that the young folks who are running this are including old folks like me, and looking at all the different ways to do stuff," Ross said.

He also flagged a second benefit: bridging the communication gap between farmers and the wider public. His verdict on the payment model was blunt. "It's not perfect, but it's not bad," Ross said.

What changes in phase two?

CANZA will expand the challenge by an additional 36,000 acres and roughly 60 Ontario farms in 2027. Phase two builds on what phase-one farmers have already learned, while broadening access to agronomic advice and implementation support.

New tools include AI-enabled systems that help farmers identify relevant opportunities and untangle program requirements and stacking considerations (combining multiple funding programs on the same acre without breaching rules).

Recruitment for phase two opens in December.

Is it worth the paperwork?

Ross's advice to farmers considering signing up: you have to want it. The cheque does not cover the effort.

"It's a good thing to do, but it does take time; it does take a commitment," Ross said. "The money does not offset the work that goes into it."

That caveat matters for budgeting. The per-acre payments sweeten the transition, but the labour, timing and agronomic learning curve remain the farmer's own. What the $17.5 million buys is de-risked experimentation — a paid runway to test nitrogen management or cover crops at scale, backed by agronomic support.

Farmers in and beyond southwestern Ontario should watch for December's phase-two recruitment window, when the 36,000-acre expansion opens to roughly 60 new Ontario farms.
