I wanted to explore what was available on line in the Board of Claims For Losses file. After Microfilm #1124 was chosen at random, I posted examples of what was found below:
The War of 1812 at Library and Archives of Canada included the War of 1812: Board of Claims for Losses, 1813-1848, RG 19 E5A, Microform: t-1124 (963 pages).
Also check the "Help" file (in this instance for #1124) for a more detailed breakdown of what's included.
More explanations (on Page 12):
