So in my case, I don’t think it applies. But that’s good to know: thanks I wonder what the Canadian situation is. My company has a few offices, and a few ships flagged as Canadian and my citizenship and license is Canadian, but I don’t work in in the Canadian fleet.
While trying to organize myself just now I found my Declaration of Prescriptions (a company document which is not private). It asks for both the name of medicine, and what it is meant to treat or control. I also found the chain of custody for the urinalysis I submitted for either my company or Transport Canada physical. It orders tests for methadone metabolite, barbiturates, benzodiazepines, amphetamines, cocaine, cannabinoids, opiates, phencyclidine and alcohol. Just putting it out there for people who might want to know if their prescription(s) might be on the list.
