John Ernest Finlayson was a piano tuner. He appears to have lived at 1932 Alberni Street sometime before 1909, since he was under that address in the 1909 Revision of Register of Voters.
However, there may be some confusion with Gilbert Hunter Finlay, who had a similar last name and who was at 1932 Alberni Street from about 1901 to 1904.
John Ernest Finlayson was in Vancouver from about 1890 to 1906, mostly working as a piano tuner and living in or near the Gastown area.

In 1891, he was living at 520 Pender Street. According to the 1891 Canada census, he was born in the United States about 1859; he was not married.
