Hi Hilary;
I received your PM. So this is your Father:
Service Number: B 17080
Rank: unknown
Surname: Gallant
Given Name(s): Arthur
Branch: Canadian Army (Active) - The Carleton and York Regiment.
In reference to your PM, if you type 1st Battalion (Carleton and York), The Royal New Brunswick Regiment into your search engine you should be able to find information on The Carleton and York Regiment that is on the internet. The Carleton and York Regiment and The North Shore (New Brunswick) Regiment were amalgamated in 1954 to form The New Brunswick Regiment:
1st Battalion (Carleton and York), The New Brunswick Regiment
2nd Battalion (North Shore), The New Brunswick Regiment
and in 1956 the prefix 'Royal' was approved, thus:
The Royal New Brunswick Regiment:
1st Battalion (Carleton and York), The Royal New Brunswick Regiment
2nd Battalion (North Shore), The Royal New Brunswick Regiment
Cheers
