[Comment] One commenter suggested that vulnerable population were not considered. [Response] 
The Challenge screening assessments are based on considerations of the available data. The various conservative exposure scenarios used are considered to be protective of vulnerable populations in Canada and do incorporate specific exposure estimates for Canadians of different ages. If information were available suggesting a specific subpopulation would be vulnerable, that information would be considered in the assessment.
