Design History and Timelines
The information provided below is taken from files available at the Canadian Archives in Ottawa. Not all the information could be found relating to the issue so there are some gaps in the history of the event. I am deeply appreciative to the staff of the Postal Archives who, very cheerful and efficiently, assisted me in my research. Canada Post Corporation is also acknowledged for their kind permission in allowing me to reproduce  philatelic material from the archives.

Don Wilson of the Saskatoon Stamp Centre has provided me with a wonderful selection of unique Canadian 1935 Silver Jubilee philatelic images. The Canadian National Archives is the second major source of images available on the subsequent pages. The latter collection (© Canada Post Corporation) have been reproduced with permission. Note - they are all watermarked.

The subsequent pages (see left hand navigation bar or below) show the stages of design and development of the different stamps.

2c - Duke of York
3c - Their Majesties
10c - Windsor Castle
13c - Britannia
