Tudor

Tudor is the family office of David Cornhill, who founded AltaGas in 1994 and served as its CEO until 2018. AltaGas remains a separate, publicly traded energy infrastructure company on the Toronto Stock Exchange. Tudor manages Cornhill's private investments and is not a corporate subsidiary of AltaGas, though its capital base originated from his AltaGas equity.

Tudor favors direct and co-investment structures over fund commitments. The office targets private midstream infrastructure, energy services, commercial real estate, and private credit, with a geographic focus on Western Canada and Texas. The family maintains control positions and avoids blind-pool fund allocations where possible, relying on its network of former operators to source deals.

No. Tudor is structured as a traditional single-family office and does not raise third-party LP capital. It serves the Cornhill family exclusively, without any multi-family office overlay or external co-investment syndicate.

David Cornhill retains final authority over Tudor's investment decisions, supported by a compact internal team across Houston and Calgary. The office does not operate with a formal investment committee structure open to non-family members.

Tudor sources opportunities primarily through the Cornhill family's multi-decade network of former AltaGas executives, energy operators, and regional developers in Western Canada and Texas. This operator-anchored approach generates off-market deal flow and avoids competitive banked-auction processes typical of institutional private markets.
