Liam Gilbert-Walsh is a Canadian tax lawyer at Barrett Tax Law. His practice focuses on disputes with the Canada Revenue Agency and on corporate-tax matters, working with individuals and incorporated clients across Canada.
On the dispute side, Liam works on CRA audit defence, proposal-letter responses, Notices of Objection, voluntary disclosures, and appeals to the Tax Court of Canada. He assists clients responding to reassessments and helps build the documentary record needed to support a client's position through the objection and appeal stages.
Liam is experienced in corporate-tax matters for owner-managed businesses and has a particular focus on owner-managed corporate files and cross-border issues, where the questions often involve how Canadian and U.S. tax rules interact for shareholders, corporations, and beneficiaries with connections on both sides of the border.
He approaches each file by mapping the client's facts against the relevant provisions of the Income Tax Act and the applicable treaty, then setting out clear, practical options. Liam is licensed in Ontario and serves clients across the country.
