Thank you so much for that question.
By my knowledge, the best data we have is on first nations communities. Canada, like the U.S., isn't collecting comprehensive data on water access across the board, so it's difficult to pinpoint other communities of need. In the U.S., for instance, we've had to use proxies, using census data and others, to first identify these communities, but then actually send physical researchers in to look.
To give you an idea of the places where we found these communities in the U.S., they're often in poorer, more rural areas. They're often in ethnically diverse areas along the border or in formerly prosperous, now poor, economic corridors, and in what are—for us—Native American territories and reservations.
I don't have any more information for you on other impacted groups, but if the Canadian experience closely mirrors the U.S. one, like I assume it does, I would be surprised if you wouldn't find other communities in need.
