Yeah, assuming Canada is just going to keep going along buying American software and services seems pretty naive. There's less capacity to build alternatives in Canada than there is in Europe, but as Europe builds out alternative ecosystems, Canadians will likely be just as eager customers as Europeans (if not more eager).

The beauty of so many of these solutions being open source solutions also means that it creates avenues for cooperation between organizations that have no official cooperation agreement.

E.g. The Austrian federal Military, the state of Schleswig-Holstein, and the city of Leon have no direct forum for cooperating on software projects, yet all three are contributing to the development and rapid adoption of Nextcloud. Canada can easily get in on this too.
