CAYRES Inc.
About
CAYRES Inc. is a Toronto-based aviation and advanced air mobility (AAM) practice founded in 2022, advising operators, infrastructure developers, and legal counsel at the intersection of Canadian aviation regulation, autonomous-system liability, and community integration. The firm describes its team as carrying 104 combined years of aviation regulatory experience.
CAYRES works in the regulatory environment being rewritten on both sides of the border: Canada's CARs Part IX reform came into force in 2025, ahead of the FAA's proposed Part 108 — a head start the firm helps clients operate inside. Its public work includes a Canadian Bar Association (Vancouver 2026) brief comparing the two regimes.
Practice areas span aviation regulation and RPOC strategy, autonomous-system liability, cross-border Canada–US operations, vertiport and drone-corridor siting, airspace data governance, Indigenous and community engagement, and privacy, cybersecurity, and cyber-physical risk in airspace. Client work covers advanced air mobility, community integration, and healthcare applications such as medical cargo delivery and remote-community access.
