Courts in Canada have recognized that because of the nature of data and international relations, it's not necessary for a company to be domiciled in Canada for Canadian courts to have jurisdiction. That's the real and substantive connection test. Courts have recognized this. If Canadian users are impacted, Canadian institutions will have jurisdiction on it.
That's why, in a case like Facebook and in other situations, we are able to assert jurisdiction independent of whether an organization is in Canada or not, provided that Canadian users are impacted.
