+#
+# CBC News reported that Ontario and Manitoba have announced plans to

+# CBC news also reported that Prince Edward Island is the first
+# province in Atlantic Canada to follow the US change, and that Quebec
+# had agreed; see <http://www.cbc.ca/pei/story/pe_daylight_20051207.html>
+# (2005-12-07).
+#
+# To reflect all this, the Canada and Winn rules have been adjusted to
+# agree with the 2007 US change.  This means we assume most of Canada
+# will fall into line.  However, Alberta, British Columbia,
+# Newfoundland, Northwest Territories, and Yukon already have separate
+# rules in our database, so for now we'll leave them alone, which
+# means that we currently assume these regions will not change their
+# rules and will disagree with the US starting in 2007.  This
+# assumption is probably incorrect, with the possible exception of
+# Newfoundland.  We plan to adjust the Edm, Vanc, StJohns, and NT_YK
+# rules as the corresponding provinces make their announcements.
