The applicant excess insurers sought a declaration that claims against a lawyer and his firm for negligent tax advice did not constitute a 'single claim' or 'related claims' under the respondent primary insurer's professional liability policy.
The lawyer had advised multiple clients to participate in a charitable donation tax shelter that the Canada Revenue Agency later disallowed as a sham.
While the claims shared common elements regarding the donation plan, one client also claimed negligence regarding a separate life and disability plan.
The court applied the test from Simpson Wigle and found that the advice regarding the life and disability plan was a distinct error, different in nature and kind from the donation plan error.
Consequently, the claims were not related, and the respondent's $2 million aggregate policy limit was available.
