Canadian registrar DOMAINSunder offers businesses a Canadian home for their email after Microsoft 365 outage

New Institutional plan for schools, health organizations and non-profits; mail stays on servers in Canada.

VANCOUVER, EDMONTON and TORONTO, November 13, 2026 — DOMAINSunder, a CIRA-certified .ca registrar since 2001, today announced replacement business email and website plans hosted entirely on servers in Canada, with hands-on help moving mailboxes from Microsoft 365, Google and other providers.

The Microsoft 365 outage this week left many Canadian businesses without email for hours. DOMAINSunder’s plans give organizations an option that does not depend on one global platform, with billing in Canadian dollars and support from a Canadian company in English, French and Spanish.

Plans (per month on a 1-year term, plus GST):

Premium Email, C$19: email at your own domain, 10 GB, spam filtering, webmail, and help setting up Outlook and phones.
Enterprise Website & Email, C$59: websites and unlimited mailboxes within 150 GB, priority support.
Institutional Website & Email (new), C$199: unlimited mailboxes within 500 GB, priority support, for larger organizations, schools, health and non-profits.

DOMAINSunder sets up the mailboxes with the same addresses, helps copy existing mail, folders and contacts, and switches the domain’s mail records (MX, SPF, DKIM, DMARC) so no mail is lost. Customers keep their domain and email addresses.

Until December 1, 2026, the November Maple Madness offer includes a free domain transfer (.ca, .com, .net, .org) when a website or email moves to DOMAINSunder, plus 10% off 1-year and 20% off 2- and 3-year plans.

“We have provided email hosting and DNS since 1991, and .ca domains as a CIRA-certified registrar since 2001. We are ready for the wave of businesses leaving Microsoft 365. We are a 100% Canadian-owned company, and we take an elbows-up approach: your email and website stay on servers in Canada, run by a Canadian company. US providers like Microsoft and Google must hand over customer data to US authorities under the CLOUD Act, even when it is stored in Canada. Our Canadian services are outside its reach,” said Blair Lowe, DOMAINSunder.
