I have been trying to track these Steeles for you with little luck.
On 1891 census Christina is listed as widow, living Uxbridge with Lillian 19, Minnie 17, Herbert 15 and Seneca 13.
On 1901 census a Lillian Steele, b 18 July 1871 which is the same birth date as a ThomasJayKemp have given on the family tree is living with father Joseph b 1842, and a Martha Hastings.
1911 census she is still with father Joseph and he has since married to Martha.
Found border crossing for a Lillian Steele, 1920 and her contact in Canada was Mr & Mrs S E Steele of Walkerville.
Joseph's obituary may have his sons and daughters listed. I could not find a death for him or Christina.
1901 and 1911 census on www.automatedgenealogy.com
The site is down right now due to a power failure but should be up and running on Wednesday.
I didn't find him on either census but have a look.
