In Canada, the applicability of the Copyright Act to communications that have international participants was elucidated in Society of Composers, Authors and Music Publishers of Canada v. Canadian Assn. of Internet Providers,  2 SCR 427, 2004 SCC 45.
The court held that:
An Internet communication that crosses one or more national boundaries “occurs” in more than one country, at a minimum, the country of transmission and the country of reception. To occur in Canada, a communication need not originate from a server located in Canada.
A real and substantial connection to Canada is sufficient to support the application of our Copyright Act to international Internet transmissions...
In terms of the Internet, relevant connecting factors would include the situs of the content provider, the host server, the intermediaries and the end user. The weight to be given to any particular factor will vary with the circumstances and the nature of the dispute. The conclusion that Canada could exercise copyright jurisdiction in respect both of transmissions originating here, and transmissions originating abroad but received here, is not only consistent with our general law but with both national and international copyright practice.
So also, in my view, a telecommunication from a foreign state to Canada, or a telecommunication from Canada to a foreign state, “is both here and there”.
That judgement reviews the situation in several other countries for comparison.
They observe that in the United States:
... there is authority [...] for taking copyright jurisdiction over both the sender of the transmission out of the United States and the receiver in the United States of material from outside that country.
The definition of “communication to the public” appears to apply Australian copyright law to communications entirely within Australia, those originating within Australia and received by an end user outside Australia, and those originating outside Australia but received by an end user in Australia
An analysis of liability in France suggests that “[c]ourts will likely assert jurisdiction not only over transmissions from France, but also transmissions into France that are alleged to cause damage”
