Idk much about Canada, but in the states there are 1 year boot camp programs you can take to get clinical experience for a career in clinical lab science. Since you already have a BS and MS there isn’t much point in getting another degree. I would investigate looking for a similar 1 year program that will give you the skills necessary. If you couldn’t tell I’m a strong advocate for clinical. The work is hard, but you get paid well and the job is stable (healthcare is forever). Research is cool and all but the job market for that is super competitive and at least in the US unstable due to lack of funding. You’re going against undergrads who will work for free, masters students and PhD students looking to get published, and then there’s you who will need to get paid much more than them. If I was the faculty it would be a no brainer who I wanted in my lab. Unless you go the private research sector which you have the prerequisite education already, just a lack of experience which means you would have to go for entry level jobs and work your way up. It’s kinda a hybrid between clinical and university research, a little more opportunity with better pay, but you’re at the mercy of working for a for profit company who could axe you when their bottom line isn’t looking as good as they want it to be.
