I suggest that Sheila write to Barnardo's on her own and ask them to check for Frederick. Barnardo's Family History Service deals with enquiries regarding records of individual children — various services are available.I had great success with using their services for one of my husband's ancestors.
In any case I decided to have a search to see what I could find. Frederick Cook appears in the online database for British Home Children found on Library and Archives Canada.

Armed with the information of his ship and arrival year, I looked in the Canada, Ocean Arrivals (Form 30A), 1919-1924 found on Ancestry. He is found there with details which may be helpful.
There are other entries on Library and Archives Canada for a Fred Cook which may be for Sheila's uncle. One is from 1924 and is a photograph published in "Ups and Downs" (magazine published by the Canadian Branch of Dr. Barnardo's Homes, Toronto), November 1924. Page Number: 11. Issue Number: 3. Volume Number: 26
She can find these entries for herself (1924, 1927 and 1928) and order copies from the Archives. I had great success using those entries to find information on the ancestor of a client.
Sheila can also search the Guardianship records on the same site. There is a great deal of information in those and they too can be ordered at a reasonable cost. Start at the Home Children 1869-1932 database online.
