The Yukon government is suing a construction company for $1.5 million over what it claims was a botched upgrade to the Mayo water treatment plant. The Department of Community Services, in a statement of claim filed in the Yukon Supreme Court on Nov. 16, alleges that the work done by Wildstone Construction and Engineering Ltd. had a number of "deficiencies," including tanks with "visible leaks and are not watertight." The government is also seeking more than $1 million from Intact Insurance, an insurance company that served as a surety for the construction contract.
