A parliamentary petition has been started to try to encourage the Canadian Government to join the Fediverse. If you want to support this petition, follow the link to Chris Alameny’s post where you’ll find links to both French and English versions of the petition. You have to be a Canadian citizen to sign the petition. We only need a few more signatures to get over the 500 needed. We’d love to see every Province and Territory represented.
I’d be happy to have an “official” Mastodon instance. If individual politicians want to engage with their constituents, they can use any old Mastodon (or Lemmy, or whatever) instance. But having government agencies use a Mastodon instance for official communications would provide some insulation from the whims of capricious corporations.
