They're invalid because there aren't organizations with those names, not because they somehow all chose hydro.ca. instead. I agree, however, that 3-level domains are hugely on the decline in Canada... and I'm quite sad about that. -Adam Get Outlook for Android<https://aka.ms/AAb9ysg> ________________________________ From: Hartmut W Sager <hwsager@marityme.net> Sent: Sunday, November 9, 2025 1:26:26 AM To: MUUG - Round Table <roundtable@muug.ca> Subject: [RndTbl] Re: muug.mb.ca decomissioned for email Good! Those provincial subdomains of .ca (resulting in 3rd level domains) have gone into almost total disuse in Canada. Even exceptions like hydro.mb.ca, where each province could legitimately want to do the same thing, is not being used much anymore. I just spot-checked hydro.on.ca and hydro.ns.ca, and they are invalid.
