First Block MTL-1 is a heat-recovery data center located in a 1.6-million-ft² repurposed industrial complex, integrating seamlessly into an active agri-food ecosystem. The project provides heat to a 150,000+ ft² year-round greenhouse—producing over 800 tonnes of vegetables annually—along with the host facility and a district loop serving adjacent buildings. The site offers 5 MW of power capacity and approximately 10,000 ft² of data hall space, structured as a retrofit for accelerated readiness. Connectivity is carrier-neutral, and deployment can be achieved within 6 months, making MTL-1 a fast-to-market, ESG-aligned compute location.
FirstBlock builds data center campuses around a simple idea: the best digital infrastructure begins with the best energy. Originating in Québec, we developed deep expertise in identifying clean, low-cost power markets and transforming them into high-performance environments for cloud, AI, and HPC operators. Today, we apply that expertise across Canada, selecting regions with stable, low-carbon power and shaping them into liquid-ready, high-density sites optimized for next-generation workloads.
Our campuses turn energy advantages into operational benefits. Advanced hydrocooling and large-scale heat-reuse systems drive consistently low PUE, improving efficiency while reducing environmental impact. Each location is prepared for rapid deployment with permitting, utility alignment, and engineering groundwork already completed, giving tenants a predictable and accelerated path to scale.
By combining energy intelligence, sustainable engineering, and a commitment to long-term cost competitiveness, FirstBlock offers operators a reliable, efficient infrastructure platform built for growth.
