You mentioned the fact that, across Canada, some organizations will have a Remembrance Sunday, or a Remembrance Day that may not be celebrated on November 11. The Legion was very instrumental in making sure that November 11 was a day that we observe nationally, the day of remembrance. Before, and in some countries still today, they have Remembrance Sundays, or Remembrance other days, but those may not fall on November 11.
For us, it's of very big significance. The 11th of the 11th of the 11th is very significant in teaching young kids that they should be remembering the sacrifices that allow them to be in the school the way they are today.
