Is a live-in nanny considered a tenant protected by the RTA?

My wife and I had a baby a few months ago and we are planning for when we are both back to work next year. We are considering getting a live-in nanny if it makes financial sense. I was wondering that in the event that we terminate the nanny's employment, whether the nanny could just decide they don't want to move out and we get stuck with a squatting tenant.

Any advice is appreciated.
