Mauryah McLaughlin is an accomplished mergers and acquisitions lawyer with a track record of leading complex, high-value transactions both in Canada and internationally. With deep strategic insight, she guides clients through every phase of a deal — from structuring and negotiation to closing — bringing clarity, efficiency, and confidence to clients who value the results produced from her leadership style.
While being seated in Calgary has given Mauryah a robust presence in the energy sector (upstream and midstream oil and gas and renewables, and energy infrastructure), her true value to clients is an M&A skillset that is agnostic to industry. Mauryah is equally adept leading transactions in health care, real estate / land assets, senior living, technology, and hospitality. She manages cross-border, multi-jurisdictional transactions as lead counsel, working with global deal teams to align legal, commercial and regulatory dimensions.
Known for her leadership on complex matters, Mauryah combines commercial acumen, a disciplined project management approach, and a collaborative negotiation style to bring value to transactions. Her clients benefit from her ability to anticipate issues, craft creative solutions under pressure, and drive towards smooth, timely closings without sacrificing structure or protection.
