Over the course of his career, HP has led numerous marquee mandates, including working two years in a row on the biggest private equity buyout deals in Canada’s history, namely the $5.2 billion recapitalization of GardaWorld by BC Partners in 2019 (Lexpert’s 2020 Private Equity Deal of the Year), the $5.125 billion recapitalization of GFL Environmental led by BC Partners and Teachers in 2018, and the launch of QuadReal Property Group in 2015-2018.

HP previously practiced as a foreign counsel at a leading Brazilian firm, where his practice was focused on project finance within the mining, oil and gas and infrastructure industries.
