Additional complications in the program, and restrictions from US government International Traffic in Arms Regulations delayed initial aircraft deliveries until 2010. Further delays resulted in expected delivery pushed to 2015. In 2013 Canada rejected the delivery of "interim" helicopters offered by Sikorsky that lacked critical mission systems. In September 2013, the Canadian government announced that they were reevaluating the CH-148 purchase, and would examine cancelling the contract and ordering different helicopters if that were the better option; by this point, Sikorsky had accrued over $88 million in late damages since 2008.
