The court affirmed that disclosing non-privileged portions of a document does not waive solicitor-client privilege over the redacted privileged portions.
Mediamix Interactive Inc. appealed a Master's order that upheld the refusal of Her Majesty the Queen in Right of Ontario to produce nine redacted slides from a 24-slide PowerPoint presentation, on the basis of solicitor-client privilege.
Mediamix argued the Master erred in finding privilege and in not finding a waiver of privilege by the disclosure of the other 15 slides.
The court dismissed the appeal, finding that the Master correctly determined the redacted slides were protected by solicitor-client privilege and that no waiver occurred, as the disclosed slides were not privileged.
The court affirmed that disclosing non-privileged portions of a document does not waive privilege over genuinely privileged parts.
