Client Work

  • Nigel acts as counsel for a large commercial insurer in handling many of the subrogated claims in both B.C. and Alberta.
  • Nigel extracted an insurance company from lengthy and expensive litigation relating to an allegedly faulty helicopter component. The final costs were less than what expert witnesses alone would have charged to testify at the trial.

Professional Defence and Regulation

  • Nigel handled a subrogated matter stemming from an accident where a driver crashed his vehicle into a power pole, resulting in a power surge in a residential neighborhood. More than 200 property damage claims resulted, each worth between $5,000 - $10,000. Nigel organized a subrogated claim on behalf of numerous insurers, suing the Insurance Corporation of British Columbia and the driver. The matter was handled much more efficiently than if each claim had been dealt with separately.
