According to one source, 3,750 Canadian women married airmen from outside Canada — Australia, New Zealand as well as the UK and elsewhere, while with the WW2 British Commonwealth Air Training Plan in Canada.
Based on the total number of airmen who graduated from the Plan, and their national air force affiliations, a rough estimate of the number of Canadian brides is 2,700 to RAF personnel, 600 to RAAF and 450 to RNZAF. There must be large error bars on those estimates, especially for RAAF and RNZAF, as there were many RAF personnel who stayed in Canada for extended periods as part of the training establishments.
For New Zealand, “about 3700 women from 37 countries, including Canada, Italy and Palestine followed their husbands and fiances to New Zealand.” that’s according to
