Cheers chaps. Thanks for the link Bruce, it was this site that showed me a photo of him (hence my question). As you know my interest is in Wally McLeod and 443 has become another strand of that. Its a brilliant site with tons of detail as you know. Through it I found what appears to be a war crime.

It does seem Aziz was at least a second-generation Canadian, but the surname is an interesting indication of diversity in the Commonwealth forces.
