"Comparison with duty to rescue
Good Samaritan laws may be confused with the duty to rescue, as described above. U.S. and Canadian approaches to this issue differ. Under the common law, good Samaritan laws provide a defence against torts arising from the attempted rescue. Such laws do not constitute a duty to rescue, such as exists in some civil law countries, and in the common law under certain circumstances. However, the duty to rescue where it exists may itself imply a shield from liability; for example, under the German law of "Unterlassene Hilfeleistung" (an offense according to provide first aid when necessary), a citizen is obliged to provide first aid when necessary and is immune from prosecution if assistance given in good faith turns out to be harmful. In Canada, all provinces with the exception of Quebec operate on the basis of English Common Law. Quebec operates a civil law system, based in part on the Napoleonic Code, and the principle of duty to rescue does apply.
To illustrate a variation in the concept of duty to rescue, in the Canadian province of Ontario, the Occupational Health and Safety Act provides all workers with the right to refuse to perform unsafe work. There are, however, specific exceptions to this right. When the "life, health or safety of another person is at risk," then specific groups, including "police officers, firefighters, or employees of a hospital, clinic or other type of medical worker (including EMS)" are specifically excluded from the right to refuse unsafe work."
I got this from Wikipedia under the Good Samaritan Law, if you read the second paragraph starting at , it reads to me that an RCMP pilot and crew have no choice but to act. To do nothing would then be negilgence on their part.
Also, if you read up under this definition, anyone, could have come to the rescue without the fear of reprisal is something went wrong:
Protection from liability 2. (1) Despite the rules of common law, a person described in subsection (2) who voluntarily and without reasonable expectation of compensation or reward provides the services described in that subsection is not liable for damages that result from the person's negligence in acting or failing to act while providing the services, unless it is established that the damages were caused by the gross negligence of the person. 2001, c. 2, s. 2 (1).

I did not see the video, so I am only going on what has been written in this thread.
Good job on the part of the aircrew, the person is alive and with their family.
