About Gahtan Law Office

Gahtan Law Office is a solo law practice based in Vaughan, Ontario, focused on information technology, health technology, e-commerce, and procurement law. Its principal, Alan Gahtan, practices in technology transaction contracting, outsourcing, and internet and e-commerce matters, and was previously a partner with the U.S. law firm Brown Raysman Millstein Felder & Steiner LLP.

Gahtan developed and taught Canada's first computer law course at Osgoode Hall Law School, in 1988 and 1989, and later taught technology law and co-taught privacy law at Seneca College. A background as a LAN administrator and as the owner and operator of computer related businesses feeds into the firm's technology contracting work, which spans software licensing, outsourcing, cloud services, and data centre agreements.

Gahtan Law Office also acts for organizations in the broader public sector, including hospitals, on procurement agreements for specialized equipment such as diagnostic imaging and laboratory systems, along with the funding and research collaboration agreements that go with them. Gahtan is admitted to the bar in Ontario and in California.
