  • Acting for a large, national geotechnical engineering firm in a number of actions arising from two large landslides. In total, more than 20 separate actions were commenced. In addition to the legal proceedings, Chris was involved in extensive negotiations with the provincial and municipal governments regarding issues of ongoing public safety. As lead counsel, Mr. Rusnak was responsible for case strategy, file management, conduct of examinations for discovery, guidance to paralegals and junior lawyers, instruction of experts and ultimately the case strategy that led to successful resolution on behalf of his client.
  • Representing a joint venture of three international engineering firms who were sued over their involvement in large-scale expansion of a waste water treatment plant. The case related to alleged design and construction defects associated with the projects waste water digesters. There were thousands of documents, many days of discovery and extensive expert evidence of a technical nature.
  • Counsel in over 100 cases relating to leaking condominiums and other buildings. These claims were generally large, complex multi-party proceedings. Damages claims range from $200,000 to $30 million, and there were often 20 or more parties involved in the claims.

Environmental Law

  • Co-counsel on behalf of a port authority  in proceedings relating to historic hydrocarbon contamination of a large industrial site. Approximately 20 parties were involved in six concurrent actions seeking more than $35 million in clean-up costs. Document disclosure was extensive and the expert evidence highly technical. The matter proceeded to trial but was resolved by out-of-court settlement before the trial was completed.

Health Law

  • Counsel in a series of matters involving claims by dozens of plaintiffs who alleged damages suffered due to sexual assaults allegedly committed while they were students of a former school teacher criminally convicted of sexual assault offences and designated a dangerous offender. Chris acted as counsel on behalf of a number of physicians named as defendants in the proceedings. The cases received significant media attention and, given its sensitive subject matter needed a carefully planned litigation strategy. In his role as lead counsel, Chris worked collaboratively with other counsel involved in the case to bring it to a successful resolution.
  • Representing numerous physicians in a variety of disputes, including the defence of a paediatric cardiac surgeon  in the British Columbia Supreme Court and Court of Appeal. The case involved allegations of professional negligence arising from a surgical procedure on a child to repair a condition known as coarctation of the aorta.
