I assume you are asking for people injured in the Halifax Explosion (6 December 1917) and not people injured in WWI in 1917.There is a ledger at the Nova Scotia Archives that lists those killed (and those who died from their injuries) in the Halifax Explosion. But this does notlist people who were injured but did not die from their wounds.I am not aware of any listing of non-fatal injuries, as it would include many thousands who suffered minor cuts or burns, many of which would not even have received medical treatment.You can search the Remembrance Book at the Archives website: (see Related Links below)
