Giselle joins Manko, Gold, Katcher & Fox’s regulatory and transactions team after working as an environmental, energy and natural resource senior associate for a leading Canadian law firm in Toronto for almost a decade. She has counseled clients on a range of environmental matters across sectors, including advising on environmental law aspects of strategic acquisitions, real property transfers and development projects, transactional due diligence, regulatory compliance and environmental litigation. Giselle regularly provides cross-border advice about environmental liability, mergers and acquisitions and environmental, social and governance (ESG) policies, programs and legislation.

Giselle has a unique understanding of the factors that impact environmental law, thanks to her previous experience working as an environmental scientist and engineering consultant. Now, she brings her technical expertise and science-based perspective to her legal practice when she helps clients assess risk, develop pragmatic solutions and build strong legal and technical cases for complex, regulatory matters and environmental litigation.

Giselle is a Certified Specialist in Environmental Law by the Law Society of Ontario. She was recognized by Lexpert Canada as a “Lawyer to Watch” in the areas of mining and energy law. She was also the recipient of the global Armenian Bar Association’s “20 under 40 Rising Stars” Award.

In her free time, Giselle enjoys hitting the tennis court, going for a run and playing the piano.

  • Representing corporations in acquisitions, including advising on environmental compliance, classifying materiality of risk and outstanding obligations, and drafting and negotiating protective environmental clauses in agreements.
  • Representing commercial landlords and tenants in negotiating favorable environmental terms in lease agreements.
