MKB Equity Partners Inc., a North American private investment firm, has completed the final close of its third flagship vehicle, MKB Partners Fund III, L.P. The fund—MKB’s largest to date—will focus on scaling growth-stage companies driving innovation across power, mobility, the built environment, and industrial efficiency, with a particular emphasis on enabling the energy transition. 

“MKB has played a pioneering role in shaping Canada’s energy transition investment landscape, and that legacy continues to guide our strategy in Fund III,” said Antonio Occhionero, Managing Partner at MKB. 

Fund III brings together a strong roster of returning and new institutional partners. Lead investors include La Caisse, Investissement Québec, and the Business Development Bank of Canada (BDC). They are joined by Canada Growth Fund Inc., Fondaction, Fonds de solidarité FTQ, BMO Capital Partners, the Trottier Family Foundation, as well as several large family offices and accredited investors. 

The firm has already begun deploying Fund III capital into three high-growth platforms: 

• Circuit – an operator of electric shuttle services providing low-emission, on-demand micro-transit solutions that advance sustainable urban mobility. 

• Cascadia – a manufacturer of high-performance fenestration products that enhance energy efficiency across the built environment. 

• IEC Holden – a contract manufacturer specializing in electric motors, generators, and components that enable industrial electrification.
