Shirley Brooks - date of death?

There was a Shirley Brooks who died on October 2, 2015: https://steelesmemorialchapel.com/condolence/shirley-brooks/ but I don't know whether that is the same Shirley Brooks who was the daughter of Mendel and Elsie Yankoo.

She is mentioned in the following documents:
https://www.geni.com/documents/view?doc_id=6000000093953385277 (death notice of Mendel Yankoo, 1975)
https://www.geni.com/documents/view?doc_id=6000000093954658093 (death notice of Elsie Frances Yankoo, 1984)
https://www.geni.com/documents/view?doc_id=6000000185454416924 (death notice of Roberta Hoffman, 2022)

In two of those, the name is spelled "Shirley" but in the third it is spelled "Shirlie". In the death notice of Roberta Hoffman (https://www.benjaminsparkmemorialchapel.ca/ServiceDetails.aspx?snum...), she is described as "the late Shirlie Brooks" so date of death must be between 1984 and 2022 inclusive.
