Career

Mark Platteel is a Toronto-based partner in the Real Estate and Financial Services Department and the Infrastructure and Construction Industry Group.

Deeply immersed in Canada's infrastructure sector, Mark advises clients across the full lifecycle of development projects, with particular emphasis on complex financing transactions, public-private partnerships (P3), and the negotiation and drafting of large-scale construction contracts. Over the course of his career, Mark has worked closely with a range of public and private sector participants – including procurement agencies, developers, contractors, financial institutions, project entities and advisors – in bringing landmark infrastructure projects to fruition across the country and throughout North America.

Prior to joining Gowling WLG, Mark served for a number of years as general counsel for one of the most active infrastructure developers worldwide. In this role, he was instrumental in advising on the legal, commercial and financing aspects of some of the most ambitious transit, bridge and road projects in Canadian history, as well as the global marketplace. This experience, and the 360-degree industry perspective it afforded, has positioned Mark strongly to help his clients navigate the myriad hurdles and major strategic considerations they encounter on their road to success.

Prior to his general counsel role, Mark was in the Financial Services Group at another large national law firm for 10 years in Toronto, working on a broad range of sophisticated debt financing transactions.
