Simple concept: one Crown, Realms are equal, all Realms share the Crown equally. I know it's tough for you, but try to wrap your mind around it, as it's quite "relevent". gbambino 

This is the central point, and gbambino is correct.   Homeontherange, wishes to emphasize the term British Crown as if it is something alien to Canada.  This is not surprising, as Homeontherange is an avid anti-Monarchist, pro-Republican.  Now, gbambino and Pter Grey only want to have the usage of the proper terminalogy inserted into the article.

The Dominion of Canada (its proper name is forbidden here at Wikipedia), is a Constitutiional-Monarchy with a Figure Head of State, i.e., the the Queen.  The Governor-General is a Figure-Head of Figure-Head of State, all to preserve tradition.  I personally seen nothing wrong with that, but then again I am not an  avid anti-Monarchist, pro-Republican.
