Judgment Summary

In Canada (National Revenue) v. Thompson, the Supreme Court of Canada evaluated the boundary between solicitor-client privilege and the statutory obligations imposed on lawyers under the Income Tax Act (ITA). The case arose when the Canada Revenue Agency (CRA) demanded that Duncan Thompson, a lawyer, disclose information related to his client accounts for tax auditing purposes. The CRA issued the demand based on provisions within the ITA that grant the agency the power to access relevant documentation to verify tax compliance. Thompson complied partially, but he withheld client-specific information, invoking solicitor-client privilege to protect client identities and related details in his accounting records.

The Minister of National Revenue sought a court order compelling Thompson to provide the client information. This demand led to a significant dispute over the extent of solicitor-client privilege, with Thompson arguing that the privilege applied not only to client communications but also to client names and financial records associated with his legal practice. He further claimed that the CRA’s request amounted to an unreasonable search and seizure under section 8 of the Canadian Charter of Rights and Freedoms.

The Federal Court initially ruled in favour of the CRA, requiring Thompson to disclose the requested records. However, the Federal Court of Appeal acknowledged that client identities within certain documents could be protected by privilege, sending the case back to the Federal Court to ascertain which client names, if any, were privileged. The Supreme Court ultimately upheld the CRA’s authority under the ITA, determining that client identities did not generally fall under solicitor-client privilege in this context. The court asserted that while solicitor-client privilege is fundamental, it can be limited by clear legislative intent, as expressed in the ITA’s provisions. The decision reinforces the scope of solicitor-client privilege in Canada, affirming it as a key element of the justice system, but one that can be circumscribed in specific, legislatively defined instances.
