Canada's Minister of Environment and Climate Change, the Honourable Steven Guilbeault, sat down with the Makers and Shakers Podcast while travelling in Ghana to announce a $20-million climate finance initiative supporting four West African nations. A former activist who once scaled the CN Tower in protest, Guilbeault now shapes the very policies he once demanded. This conversation captures that rare and compelling arc: from the streets to the cabinet table.
A photograph follows Steven Guilbeault wherever he goes. In it, he is dressed in bright orange overalls and handcuffed by Toronto police at the base of the CN Tower. The year was 2001, and Guilbeault, then a prominent climate activist with Équiterre, had scaled the exterior of the iconic structure to protest Canada's inaction on climate change. It was a dramatic and deliberately visible act, designed to force a conversation that official channels seemed unwilling to have.
Two decades later, that conversation has moved indoors, and Guilbeault is the one leading it. As Canada's Minister of Environment and Climate Change under Prime Minister Justin Trudeau, he now sits on the other side of the table, drafting legislation, negotiating international treaties, chairing United Nations working groups, and travelling the world to deliver the climate commitments his younger self marched and climbed to demand. It is a trajectory that is genuinely rare in public life, and it raises a question that hangs in the background of any conversation with him: What does it feel like to become the institution you once confronted?
We caught up with Minister Guilbeault this week as he travelled through Accra, Ghana, where he was announcing a significant phase of Canada's international climate finance program. The timing felt appropriate. This is a man whose entire career, before and after entering politics, has been defined by urgency.
A $20-million commitment to West Africa's climate infrastructure
The immediate purpose of Guilbeault's West African visit was to announce the second phase of a Canadian climate finance project administered by Novosphere, a Canadian non-profit. The initiative targets four countries — Ghana, Liberia, Togo and the Gambia — providing the data infrastructure those nations need to measure, report and verify their emissions reductions. These MRV systems (Measurement, Reporting and Verification) are far less glamorous than zero-emissions vehicles or solar farms, but they are arguably just as important.
"We're actually moving into phase two, which would provide $20 million for each of those countries," Guilbeault told us. "We already have an agreement with Togo, and yesterday in my meeting with Ghana's environment minister, they announced that Ghana would be participating in phase two as well."
Without reliable emissions data, countries cannot access the international climate finance they need to build clean infrastructure, because funders require transparent, comparable reporting before committing capital. Guilbeault's point was straightforward: Canada is helping these nations build the plumbing that makes everything else possible. The funding flows not just from Canada, but from a network of multilateral institutions, including the World Bank and the African Development Bank.
The plastic pollution crisis, seen from a beach in Accra
Emissions data was only one piece of the agenda. Guilbeault also visited a beach in Accra with a local NGO, and what he described there was striking not just for its environmental scale but for its diplomatic candour.
"Some of it is generated locally, but some of it is actually coming from Canada," he said, referring to the plastic waste washing ashore. "We ship things to Ghana, plastic waste or theoretically plastic that should be recyclable, but that is not recyclable, and it just contributes to more waste in Ghana."
He added that textiles are proving to be an even larger problem than plastic. Fast fashion from wealthier nations, discarded and shipped abroad under the pretence of recycling, is accumulating in developing countries that lack the infrastructure or the obligation to manage it.
This kind of accountability, a sitting Canadian minister acknowledging on the record that Canada is part of the problem, reflects something of the activist's instinct still visible in the politician. It is not the language of spin.
Canada and Ghana at the UN; co-chairing a historic resolution
The conversation on plastics connects to something larger. Earlier this year, at the United Nations Environment Assembly in Nairobi, more than 170 member states agreed to a historic resolution launching negotiations toward the world's first legally binding international treaty to end plastic pollution. Canada and Ghana co-chaired the working group that made it happen.
Inger Andersen, the Executive Director of the UN Environment Programme, called the resolution "the most significant environmental multilateral deal since the Paris accord."
Guilbeault framed Canada's co-facilitation role with quiet pride. "We have a very good collaboration with the government of Ghana on the environment, and recently on climate change and now on plastics as well." The negotiations are expected to produce a treaty framework within two years.
Doubling down on climate finance
The visit to Ghana also came in the context of Canada's broader international climate finance commitments. In the lead-up to COP26 in Glasgow last year, Canada doubled its pledge, moving from $2.65 billion to $5.3 billion over five years. The funds are directed at four priorities:
- Clean energy and coal phase-out
- Climate-smart agriculture and food systems
- Nature-based solutions and biodiversity
- Climate governance
Beyond the total amount, Guilbeault highlighted a shift in how the money is being allocated. Historically, the global ratio of climate finance has skewed heavily toward mitigation (reducing emissions) at roughly 70%, with only 30% going to adaptation (helping communities cope with climate impacts already underway). Canada has moved that ratio to 40% mitigation and 60% adaptation, a meaningful step toward the international informal target of a 50-50 split.
"There's still some room to improve, but we have already made significant improvements," he said. It was a careful, honest answer. Not a victory lap.
Net zero by 2050: The domestic agenda
The international dimension of Guilbeault's role is matched by an equally ambitious domestic agenda. In late March, the Trudeau government released its emissions-reduction plan, a roadmap outlining how Canada intends to cut greenhouse gas emissions by 40% before 2030 and reach carbon neutrality by 2050. The plan contains several headline commitments:
- A zero-emission vehicle mandate requiring automakers to sell at least 20% ZEVs by 2026, 60% by 2030 and 100% by 2035
- A clean electricity standard targeting a net-zero national grid by 2035
- An emissions cap on the oil and gas sector, with consultations launching in the coming weeks
- More than $9 billion in new investment in clean technologies, bringing Canada's total climate investment since 2016 to close to $110 billion
Each of these measures represents a policy lever that, a decade ago, Guilbeault was demanding from the outside. Now he is the one pulling them.
The activist's instinct in the minister's chair
The David Suzuki Foundation, one of Canada's most prominent environmental organizations, applauded Trudeau's decision to appoint Guilbeault to the environment portfolio. The foundation described him as a well-respected leader from the environmental movement and said the appointment "sends a strong signal for action." It was a rare moment of alignment between civil society and government, rooted in the credibility Guilbeault brought to the cabinet.
That credibility, earned over decades of frontline advocacy, is both his greatest asset and his most complicated inheritance. Environmental advocates who once stood beside him now scrutinize his every policy decision. The standards are higher because he helped set them.
What comes through in the conversation is that Guilbeault has not abandoned the urgency that sent him up that tower in 2001. He speaks about the circular economy with the same conviction he likely brought to protest signs. He names Canada's complicity in plastic waste without flinching. He acknowledges the gap between where Canada is and where the informal international targets say it should be.
Where the orange overalls went
The story of Steven Guilbeault matters beyond climate policy. It is a story about what happens when someone who has spent their career demanding change steps directly into the machinery of government. The tension never fully resolves, and perhaps it should not. The best public officials carry some friction between the idealist they were and the pragmatist they must become.
That friction, honestly, is what makes Guilbeault worth listening to. He is not a career politician who discovered climate change as a portfolio assignment. He is someone who gave decades to the cause before ever setting foot in a cabinet room. The policies he is now implementing, the vehicle mandates, the electricity standards and the emissions cap on oil and gas, are not abstract to him. They are the answer to demands he was making when most of his current colleagues were focused on other things entirely.
Speaking from Accra, surrounded by evidence of both progress and the distance still to travel, Guilbeault seemed comfortable in that tension. The orange overalls are long gone. The urgency, clearly, is not.
