Thank you, Mr. Speaker, and I thank the Member for that question. I'm happy to tell the House the department is currently reviewing the 2003 environmental guidelines for contaminated sites remediation. This work is being done with new information on remediation criteria from the Canada Council of Ministers of the Environment as well a new data that has come on arsenic in the Yellowknife area.

ENR recognizes that the 2003 guidelines is dated, and the updating environmental guidance is standard practice as new data and scientific research is available. This work is nearly completed and will be finalized in the fall of 2021. Thank you, Mr. Speaker.
