Telesystem International Wireless

François-Charles Sirois serves as President and CEO, leading day-to-day investment activities. Founder Charles Sirois remains Chairman and involved in strategic direction. The firm operates with a lean Montreal-based team drawing on the Sirois family's decades of operating experience in global telecommunications.

The capital base originated from Telesystem International Wireless, which Charles Sirois co-founded with Ted Rogers in 1995. The company built and operated cellular networks in markets including Brazil, Romania and the Czech Republic before selling its Eastern European operations to Vodafone for roughly $4.2 billion in 2005 (per The Globe and Mail, 2005). Proceeds were recycled into a permanent-capital investment vehicle.

Yes, co-investment is a central part of the strategy. The Caisse de dépôt et placement du Québec is a frequent partner on telecommunications and technology deals. This relationship provides the firm with access to larger-scale transactions than typical family offices of similar size, leveraging CDPQ's balance sheet and due-diligence resources.

Ted Rogers co-founded Telesystem International Wireless alongside Charles Sirois in 1995. While the operational partnership ended with the company's sale of its core assets, the relationship established Sirois's credentials in mobile telecommunications and created the network that underpins the family's investment activities today.

Yes. Charles Sirois founded the Enablis Entrepreneurial Network, a nonprofit supporting entrepreneurs in developing countries through peer lending and mentorship. The family also supports the McPeak-Sirois Group for Clinical Research in Breast Cancer and operates the TRIOOMPH Foundation, focused on educational and community initiatives in Quebec.
