Team chat

Canadian alternatives to Slack

Slack: Slack offers Canadian storage, but you have to choose it, and it may depend on your plan. It is owned by a US company, so the US CLOUD Act can require it to produce data it controls, wherever that data is stored.

Tier 4: US-owned, Canadian region

Run it yourself

Software you install on servers you choose. The vendor never holds your data.

  • ElementSelf-hosted: Run it yourself

    Element (Matrix chat and calls) on Element Server Suite, self-hosted

    Stored in Canada?
    If you host it yourself
    Owner
    Element Creations Limited (UK, headquarters), with entities in Germany, France and the US
    Servers run by
    Your own servers, or Element's hosted service on AWS · US company

    Built on the open Matrix standard. Self-hosted on Canadian infrastructure, the vendor never holds your messages.

  • MattermostSelf-hosted: Run it yourself

    Mattermost (self-hosted or Mattermost Cloud)

    Stored in Canada?
    If you host it yourself
    Owner
    Mattermost, Inc. (Palo Alto, CA)
    Servers run by
    Your own servers, a hosting partner, or Mattermost Cloud on AWS · US company

    Open source and self-hostable, so it can run on Canadian infrastructure. For data outside the US, Mattermost points to self-hosting or a hosting partner.

  • Rocket.ChatSelf-hosted: Run it yourself

    Rocket.Chat (self-hosted or Rocket.Chat Cloud)

    Stored in Canada?
    If you host it yourself

    Servers run by
    Your own servers, or Rocket.Chat Cloud on OVH and AWS · US company

    Rocket.Chat can be deployed "on your own server", so it can run on Canadian infrastructure. Its cloud regions are the US and the EU.

  • ZulipSelf-hosted: Run it yourself

    Zulip (self-hosted or Zulip Cloud)

    Stored in Canada?

    Servers run by
    Your own servers, or Zulip Cloud on AWS, DigitalOcean and Google (subprocessor list) · US company

    Self-hosted, it can run on Canadian infrastructure; Zulip Cloud has no Canadian option on the pages read.
