Background

In 2009, the Calgary Airport Authority (CAA) entered into a construction agreement with Iona Contractors Ltd. for Iona to improve CAA’s north airfield. By October 2010, the work was substantially complete; however CAA withheld further payment to Iona on the basis that some of Iona’s subcontractors remained unpaid. Iona assigned into bankruptcy and a dispute arose over the entitlement to the withheld amounts (the Funds).
