The odds of a post here catching a descendant's eye are a little slim, although these things do happen.
Others might be able to help trace them, though. Knowing where in Ontario is important. In 1871, the subdistrict was Logan and the district was Perth North -- in southwestern Ontario between Toronto and London. I can't see the family in the 1881 census - have you found them?
http://www.collectionscanada.gc.ca/databases/census-1881/001049-100.01-e.phpThey had more children after 1871 - mother Eliza Sophia Gill, it can help to know for searching:

Richard R, 1872
Eliza S, 1839
C Eleanora H, 1865 (presumably Charlotte)
Caroline E, 1870
Maria L M, 1877
Alice, 1882
You can search for marriages (to 1936) and deaths (to 1991) for the other children here, if others of them relocated to BC:

Eliza Sophia Short died in Vancouver in 1927, e.g. I'm not finding much for the others ...
Eliza, Richard and Alice were in New Westminster, BC, in 1911:

http://vitalstats.gov.mb.ca/Query.phpCaroline Emily Short died in 1939, aged 68.
Frederick William Howell Short married Emma Graham in 1891.
They are in Manitoba in 1911 with daughter Elsie Gertrude:
http://automatedgenealogy.com/census11/View.jsp?id=66014&highlight=5&desc=1911+Census+of+Canada+page+containing+Fredrick+William+Holand+Shortand I had missed them in 1911 -- they are on the same page as Eliza and the other children.
However, he died in Ontario in 1941:
https://familysearch.org/pal:/MM9.1.1/FLGK-L4RElsie married John Gordon Turiff in 1916 in Manitoba.
There is an S Turiff in Manitoba in 1911, aged 18 (Elsie was 17) and only two others in Canada (not counting very likely mistranscriptions).
Hm, I suspect a misspelling of Turriff, which shows almost 100 listings in the phone book at present -
www.canada411.ca. Yes; here is John Gordon in 1911, also in Marquette:
http://automatedgenealogy.com/census11/View.jsp?id=66010&highlight=36&desc=1911+Census+of+Canada+page+containing+John+Gordon+TurriffHe was killed in 1918 in France:
http://www.veterans.gc.ca/eng/collections/virtualmem/Detail/558170Elsie died in BC in 1949. It seems unlikely they had children. He enrolled in the CEF in 1916 three weeks before his marriage:

Trying to complete the set of children now that I've started! --
Edward in 1916 in Marquette:
https://familysearch.org/pal:/MM9.1.1/KMGV-5K9with wife Sarah and stepdaughter Margo Hackey.
George in 1916 in Marquette:
https://familysearch.org/pal:/MM9.1.1/KMGV-5KWwith wife Esther and two children:
Hazel, 4
Clara, 2
and "Eloma" Short, aged 50, sister, evidently Charlotte Eleanora.
I don't see any further trace of the daughters.
But finally, some better news for finding descendants: Lucy (Maria) and Mark Lumly in 1911 in Vancouver:
http://automatedgenealogy.com/census11/View.jsp?id=61801&highlight=3&desc=1911+Census+of+Canada+page+containing+Mark+Lumlywith two children, both daughters, aargh (for finding their descendants):
Harriat, 11
Rita, 9
Danged if I can find them in 1916 at familysearch, but they may be up to the middle name tricks:
Mabel Rita Lumley was born Dec 1902 in Vancouver ... no marriage found in BC.
And nothing found for Harriat. But actually, they were Maria Lucy's stepdaughters anyway since she married Mark in 1907 ...
