Yes. In PV-3, the Six Nations of the Grand River was looking to ensure that the Government of Canada understood that homes be included. I can read out PV-3.
Rather than simply saying, “from a public or private water system”, PV-3 goes on to explain it's for “all residents, legal occupants and users of buildings”, and then has an additional “greater certainty” that “the buildings referred to” in that earlier section “include homes”. It goes on to share “uses of water” in homes.
