The federal government is underestimating the cost of cleaning up its contaminated sites. The parliamentary budget officer says it’ll cost about 2-billion dollars more than the government expects to clean-up the 10-thousand sites across the country with the total bill pegged at around 7-billion dollars. One of those sites is Killbear Point in Carling where the Department of Fisheries and Oceans has found petroleum hydrocarbons in the soil and metal materials in the sediment. The DFO has completed detailed testing and remediation and risk management is planned. Environment Canada runs the program, identifying sites that could pose a threat to human health or the environment.
