Thank you, a very wonderful question.
I want to take myself as an example. I graduated from a nursing program in Ontario and moved almost immediately to B.C. for my first job. There weren't jobs in Ontario at the time. I have moved back and forth between two provinces over most of my career.
So having a unique identifier would enable us to know where I am, first of all, and what my profile is. It would enable us to more quickly deploy me and my skills in a time of pandemic planning or response, as well as any other kind of situation in which we needed to rapidly deploy health care professionals.
We do know that our provinces and territories are onside with this, from the viewpoint that it would help them in their regulatory activities. Unique identifiers are also in the interest of the public, because if I have an offence against me or some practice issue, that becomes evident in my profile. So I cannot slip through the cracks by simply moving to another province.
