On the Ancestry website there is a Robert Dickson, shown as born Carluke in 1885 - with a wife Joan - who died on 25th April 1939 in Hamilton, Wentworth, Ontario. Gives him a birth date of 31 Dec 1885 though. (To clarify - it was Robert who died on this date, not Joan!!)
The death cert is shown -- which also reveals he had been a soldier.
maybe you will find him on emigration records or the Canadian census records.
