# Nipigon (EST) and Rainy River (CST) are the largest that we know of.

+# msb@sq.com writes that an article in the 1997-10-14 Toronto Star
+# says that Atikokan, Ontario currently does not observe DST,
+# but will vote on 11-10 whether to use EST/EDT.

+# Ontario Time Act (1990, Chapter T.9)
+# </a>
+# says that Ontario east of 90W uses EST/EDT, and west of 90W uses CST/CDT.
+# Officially Atikokan is therefore on CST/CDT, and most likely this report
+# concerns a non-official time observed as a matter of local practice.
+# For what it's worth, Shanks (1995) says that Atikokan has agreed with
+# Rainy River ever since standard time was introduced.
