A reader asked if I would post on the proper protocol to address Canadian dignitaries such as the Prime Minister or other Ministers in the government. This government site gives you that information and more.
I will add it to my Favourites on the side bar of the blog under Addressing Dignitaries Protocol for everyone's convenience, but I would suggest you add it to your own Favourites as well. This is a must-have resource.
For my readers from other countries, you will note there is a section for foreign dignitaries and if you click on that it will give you the proper form to address just about anyone in the world.
