Absolutely. If it's of interest, I can certainly provide elaboration on that.
Essentially what we did was we embarked on a consultation to get a sense of what exactly vulnerable populations are, from a Canadian perspective. We had the work that we do under CEPA and under the chemicals management plan. We established a vulnerable populations panel. We brought forward a range of different representatives who represented different groups of vulnerable populations. We listened to them. We heard them. We also looked internationally to get a sense of what other jurisdictions identified as definitions of vulnerable populations. We essentially then pulled together a consultation document that went out for discussion, in terms of vulnerable populations. That is, ultimately, how we landed on the definition that we currently have, or that is proposed, with regard to vulnerable populations.
The purpose behind that was to really get a sense of the different age groups and the different categories of Canadian people who could be vulnerable, and also get a sense, from an exposure perspective, of what this could mean.
