Yearbook Update - 1916

A series of photographs from the Vancouver Archives labelled 58th C.F.A.  Exhibition Grounds Vancouver from the Stuart Thompson fonds. Stuart Thompson took most of the group photographs of the 68th Overseas Depot Battery. 
The questions are:
Is there a typo in the labeling of all these photographs (58 should read 68)?
Do these pictures portray 59th Overseas Depot Battery that are simply training at the Exhibition Grounds in Vancouver?
Were these photographs actually taken at the Exhibition Grounds in Victoria?
