Thank you, Chair, for the question.
My understanding is that the regulation regarding the treatment of sewage is done through Environment Canada, through the waste-water systems effluent regulations. Any authorization that was done in respect of the incident Mr. Strahl was referring to would have been through that mechanism, which is an Environment Canada regulation. My understanding is that the regulation effectively prohibits the deposit of raw sewage into waters out of treatment systems that treat more than 100 cubic metres, I think, in terms of volume. That would apply in the context of port authorities as well.
