After reviewing the documents and researching the Canadian National Steamship Company, it appears my grandfather was indeed in Crown service when my mother was born in 1937.
Key findings:
He served as a Steward on the Lady Hawkins (CNS vessel) during documented wartime voyages in 1940-1941
The Canadian National Steamship Company was a Crown corporation - making employees Crown servants
The Lady boats operated regular Caribbean passenger service from 1928-1952, so he was likely working this route in the 1930s when he met my grandmother in Cuba
He continued merchant marine service throughout the war, later serving on the El Lago where he was killed in October 1942
So the timeline appears to be:
1930s: Steward on Lady boats (CNS) - meets grandmother in Cuba ✓
Crown service1937: Mother born while he's employed by CNS ✓
Crown service1940-1941: Documented service on Lady Hawkins ✓
Crown service1942: Transferred to El Lago, killed in U-boat attack
I need to confirm some of this but I think it may establish he was a Crown servant throughout the relevant period for citizenship purposes. The Canadian National Steamship Company being government-owned is the key factor.
