The investment reflects Amrize’s commitment to strengthen supply of local cement to meet growing construction demand in Quebec and across Canada. It is part of Amrize’s plan to invest across its operations to expand production, improve efficiency and best serve customers.
Located in Saint-Constant, Quebec, the modernization will include:
- State-of-the-art Operational Efficiency: Modern, high efficiency equipment will improve production, energy efficiency, storage and logistics.
- Enhanced Sustainability: The plant expects to improve its net carbon footprint¹ by over 40% by 2035, offering the lowest carbon emissions per tonne of cement in Eastern Canada.
- Strengthened Local Manufacturing and Jobs: The modernization will expand the plant’s production capacity by 300,000 tonnes to a total of 1.2 million tonnes annually, and grow the plant’s workforce by 25% with local teammates.
From the Saint-Constant plant, Amrize plans to offer ‘Manufactured in Quebec' cement, guaranteeing production—from raw material and processing to final manufacturing—is carried out in Quebec, supporting local jobs and communities.
The modernization comes as the Government of Canada and the Government of Quebec announce plans to invest nearly $10 billion over the next decade to expand local infrastructure, public transportation, healthcare facilities and housing.
"Our investment in Quebec will modernize our cement plant into the most advanced and sustainable plant in Eastern Canada," said Jaime Hill, President, Amrize Building Materials. "As the Canadian and Quebec governments invest to shape the future of the province, this modernization ensures that it is built with reliable, local and highly efficient cement. We are proud to support Quebec’s jobs, economy, communities and infrastructure for decades to come."
Measures to reduce GHG emissions are supported by the Government of Canada, through the Low-Carbon Economy Fund (LCEF), as well as by the Government of Quebec, under the ÉcoPerformance program and the Support Measure for the Decarbonization of the Industrial Sector (MADI), two initiatives stemming from the 2030 Green Economy Plan and funded by the Quebec Carbon Market.
"By helping Canadian cement companies adopt cleaner technologies, we are reducing emissions, improving energy efficiency, and strengthening a low-carbon economy," says the Honourable Nathalie Provost, Secretary of State (Nature). "Today's announcement will support the modernization of the Amrize cement plant, sustain local jobs, and help build a greener future for Saint-Constant."
With a legacy of building Quebec for over 70 years, Amrize has helped shape many of the province’s most important landmarks and infrastructure projects from the Robert-Bourassa Generating Station and the Montreal Metro Blue Line to the Samuel Champlain Bridge, the Île-aux-Tourtes Bridge, the Montreal Trudeau International Airport and the Place des Montréalaises.
