Mylany David practices commercial and real estate law, specializing in commercial, real estate and industrial transactions, and in the development and implementation of energy and infrastructure projects, particularly in the Agritech sector*.

Mylany represents real estate promoters, project developers, financial institutions, lessors and lessees, advising them on the myriad issues inherent in developing and completing projects, which can involve acquiring the necessary land, obtaining environmental permits, securing financing, negotiating purchase and sale agreements, appearing before administrative tribunals, etc. By identifying and assessing inherent risks, after having determined the social acceptability of a project, Mylany negotiates win-win agreements that have the buy-in of all stakeholders.

Whether the project involves public-private partnerships or large procurement and construction components, Mylany has acknowledged expertise in managing the legal aspects of projects. In addition to negotiating agreements for the supply of equipment and electricity (PPA), and for securing the necessary property rights for the project (whether on private or public land), she ensures that the project complies with all bylaws and regulations and meets her clients’ goals. Also known for her inspiring leadership, Mylany is instrumental transactions requiring the supervision of extensive due diligence teams. Finally, her understanding of this area earned her a nomination in 2017 as a director of the management committee of the Green Fund.

Mylany was named as one of Canada’s Leading Infrastructure Lawyers by the Lexpert Special Edition on Canada’s Leading Infrastructure Lawyers 2020, 2018, 2017, 2016 and 2015. She is consistently recommended as a leader in the commercial and energy (electricity) fields.

* Agritech (or Agtech) commonly refers to innovative technologies in agriculture.
