Help with Canadian ancestry?

I'm posting here in the main project since this crosses multiple borders. :)

I'm wondering if anyone with access to Canadian records can help connect Susan Ann Morley. She was born in Texas to parents from Montreal, then moved to The Bahamas as an infant. Her daughter Emily is the first-ever Bahamian rowing competitor, plus her husband (Emily's father) competed in swimming in 1984, so I'd really like to connect them into the WFT.

There are some other accomplished relatives who might provide clues: Private is a Canadian photographer, and Tony O'Malley is an Irish painter.
