1911 census is the last one released.
Births released to 1912; marriages to 1926 and deaths to 1936.
Birth registration:
Hilda Victoria, 23 May 1907, d/o Jno Tuck & Sarah Geddes, Parry Sound.
She is the only child that I found registered but at least it gives Sarah's maiden name.
I don't see a marriage registered for them either.

I don't see any John Tuck of the right age on 1901 census in the area.
There is a family tree on Ancestry.ca with a Sarah on it but it is a bit confusing.
It has all her iinformation re marriage, children from 1911 census etc but it has her joining up for WW1 from Winnipeg under name Sarah Elizabeth Tuck and as a professional nurse. Next of kin is given as aunt Sarah Elizabeth Baker of Neepewa Manitoba. I think this is not the same person. Why would she join up with a mob of kids at home? Her birth date is given as 5 June 1884. Someone is on the wrong track with their genealogy maybe.
