I’m a Senior VP who has previously hired large law firms. I was referred to Counter to fix a tax dispute from the sale of an investment property I co-owned with two non-residents. I wish I hired Counter sooner.

- David Cuddy, Senior Vice-President, Finance & Business Operations, CFL

Counter worked smart and hard to help us win the appeal. We worked together to reorganize all the evidence, and we presented a clear and coherent case. We won and avoided roughly $600,000 in tax, penalties, and interest.

- Fred Levy, CPA, CA, LPA, MBA

Simply the best is how I would describe Counter Tax. They were on top of everything that CRA and the MOF were throwing at us, and kept us informed and well-advised on next steps. By the way, they won both cases.

- John Locke, President, Campbellford Wholesale Inc.
