Quite frankly, I am not competent to decide on the jurisdiction conflict between provincial and federal governments.
What I can tell you is that from the point of view of the operation of a laboratory, it is highly desirable that proper procedure and regulation be promulgated and enforced to ensure that the necessary laboratory work is conducted safely from the point of view of those who do it and from the point of view of public health considerations, while ensuring that the diagnostic work is done.
What is the line between provincial and federal jurisdictions? I am not a lawyer. I cannot help you there.
