Canadian amateur radio operators may use their stations to transmit international communications on behalf of a third party:

Canadian regulations do not prohibit amateur radio operators from passing international communications on behalf of a third party (someone who is not the licensed operator). Therefore, Canadians are generally permitted to do so from their end simply because it is not explicitly forbidden. While Canadian rules allow it, amateurs must also ensure that the foreign country involved also allows third-party traffic. However, from a strictly Canadian regulatory standpoint, it is allowed because Canada does not prohibit it. Distractors involving remuneration are highly incorrect because amateurs can never accept payment for passing messages. Furthermore, special written authorization from Innovation, Science and Economic Development Canada (ISED) is not required for standard third-party traffic.
