 # Canadian holiday definitions for the Ruby Holiday gem.
-# Updated 2018-03-02.
+# Updated 2026-08-19.
 #
 # Notes:
 #  - 'Family Day' in various provinces are only celebrated after certain years: http://www.timeanddate.com/holidays/canada/family-day
 #  - 'Family Day' for New Brunswick after 2018  http://www.gnb.ca/legis/bill/FILE/58/3/Bill-67-e.htm
 #  - 'National Aboriginal Day for Yukon' Bill 2 received Royal Assent on May 8, 2017. http://www.gov.yk.ca/news/17-075.html
+#  - 'National Day for Truth and Reconciliation' is statutory in BC (Employment Standards Act, 2023) and PEI (2021).
+#    In Alberta and Manitoba it is informal here: Alberta leaves it to employer discretion, and while Manitoba made it a
+#    general holiday on 2023-12-07, we only apply it going forward. Applied after 2026 so historical dates are unchanged.
