Change of French title of Sub-Lieutenant in Canadian navy

[jrichardn2]

The lowest two commissioned ranks in the Canadian navy are, in English:

Sub-Lieutenant (equivalent to U.S. Lieutenant, Junior Grade)
Acting Sub-Lieutenant (equivalent to U.S. Ensign)

I read in Wikipedia that until 1998 these ranks were, in French:

Sous-Lieutenant
Sous-Lieutenant (Intérimaire)

Since 1998 they've been:

Enseigne de vaisseau de 1re classe
Enseigne de vaisseau de 2e classe

These new titles are apparently shared with the Belgian and French navies. But (for example) Canadian generals' rank titles in French reflect their English origins, not their French equivalents. E.g., the French title of OF8 is lieutenant-général not général de corps d'armée.

Anyway, does anyone have insight into why the rank titles were changed? Was it to bring them into line with the other French-speaking NATO members?
