Expert guidance through a complex data breach response
Our company faced a significant data security incident involving customer PII. We engaged Antoine Guilmain at Gowling WLG based on his national reputation in privacy law. Antoine provided exceptional, clear-headed counsel throughout the entire response, from regulatory notifications to crafting our communications strategy. His deep knowledge of the legal landscape was evident and gave our leadership team immense confidence during a stressful time. The outcome was far better than we anticipated. While his expertise is top-tier and worth the investment, coordinating schedules for urgent, non-crisis follow-ups could occasionally be smoother. Overall, I would not hesitate to recommend him for any complex data security matter.
