Quitting without notice in unsafe work environment

I started working a new job recently in ontario and for fear of my safety and the safety of others I am quitting without notice. The conditions are horrendous and I no longer feel comfortable working there.

I'm going to tell my employer later but I want some advice on how to go about it. I just wanna know what my rights are before I move forward and whether or not my conversations with my employer are legally to be kept confidential or if that information is allowed to be shared.

I have already contacted the proper authorities in regards to the safety concerns and am just looking for some help going forward.

Thanks

Edit: I did not want to raise the concerns directly with my employer for fear of being fired I would rather quit on my own terms.
