General Fusion, headquartered in Richmond, British Columbia, is developing magnetized target fusion (MTF) — a distinctly different approach from the tokamak and laser-driven methods pursued by most fusion competitors. Their Lawson Machine 26 (LM26) achieved first plasma in March 2025 and is designed to reach fusion conditions above 100 million degrees Celsius, with scientific breakeven-equivalent shots targeted for 2026. The company announced plans to go public in January 2026, with proceeds funding LM26's full program. General Fusion has also partnered with Canadian Nuclear Laboratories to advance commercial power plant design.
MTF matters because it offers a potentially simpler and cheaper path to commercial fusion than competing approaches. Rather than sustaining a plasma indefinitely (tokamak) or igniting fuel pellets with massive lasers (NIF), MTF compresses a magnetized plasma using mechanical pistons — a brute-force approach that uses conventional manufacturing rather than exotic materials. This could dramatically reduce the cost and complexity of commercial fusion reactors compared to ITER-style designs.
Canada hosting a credible fusion company is strategically significant because fusion energy would eliminate the fundamental constraint on clean energy supply. General Fusion's approach, developed over two decades of Canadian R&D, represents a distinctly non-American path to fusion that could give Canada intellectual property and industrial capability in what may become the defining energy technology of the 21st century. The CNL partnership ensures that regulatory and safety frameworks are developed in parallel with the technology.
