I checked the on-line telephone directory
www.canada411.caand there are only 6 Ellott's listed for Canada and they are is Ontario and British Columbia. One could be related to your Percy George.
Also information for Percy could be transcribed as Elliott. On his attestation papers, the next of kin is actually down as Elliott.
Did Percy marry in 1902 in England. On both ancestry and the free BMD site, there is a marriage for Percy George Ellott in Dec. 1902 in Camberwell. The other listing for females at the same time are Maude Fanny Ayers and Mary Ethel Lee. Do you know if your Percy married one of them?
Passengers lists has
Percy Geo Elliott, male, age 26, b. abt 1885
Date of Arrival: 21 July 1911, Quebec
Teutonic
He is listed as a farmer and single but is headed for Toronto so could be your Percy. If so, he will not show up on the 1911 Census of Canada. Hope this helps and gives you something to work on. did any other family members come to Canada either before or after Percy. If he was married, do you know what happened to his wife.
