Citizenship by descent wait times

How long did everyone wait for their application to be processed. I'm going through my great grandfather who left in 1891. He was from the Austrian partition. I have his birth records from his towns registry. I also have confirmation from the Canadian government that he never naturalized. He was a farmer, and my grandfather was born in Canada in 1938 did not work for the government and never naturalized anywhere. I have every ones birth and marriage certificates to get to me.

Edit: I plan on going alone through the consulate in Toronto.
