Sure. Pretty much certified copies of documents proving your Canadian-born ancestor was born in Canada (commonly birth or baptism records), and certified copies of birth records linking you to them through every generation.
For me, I had access to my, my father’s, and his father’s, birth certificates. Easy. I ordered a birth certificate for my great-grandmother from the US county in which she was born to Canadian-born parents. I also ordered birth/baptism records for both my great-great-grandparents from the cities/provinces in which they were born. Packaged it up along with a family tree and sent it off. Still waiting, but feel pretty confident I’ll get word back that Canada recognizes my citizenship through descent.
