How do I go about getting a new copy of a deed?

I’m looking to sell a property we inherited ages ago in Newfoundland. My parents are both elderly and have no idea where the original deed would be, it’s likely gone. How do I go about getting a copy? I feel like I’m going in circles looking online.

(I’m in Ontario so online or over the phone vastly preferred.)

ETA: I asked my parents and there was no will when it was left to them, but they’ve been paying taxes on the property and the local govt has written to my mother about the house. So they’re down on paper somewhere, but I have no idea if the deed was ever in their name.
