# entry since our cutoff date of 1970, so we can move

+# # From Paul Eggert (2006-07-09):
+# # Shanks & Pottenger write that since 1970 most of Ontario has been like
+# # Toronto.
+# # Thunder Bay skipped DST in 1973.
+# # Many smaller locales did not observe peacetime DST until 1974;
+# # Nipigon (EST) and Rainy River (CST) are the largest that we know of.
+#
+# In the (Toronto) Globe and Mail for Saturday, 1955-09-24, in the bottom
+# right corner of page 1, it says that Toronto will return to standard
+# time at 2 am Sunday morning (which agrees with the database), and that:
+#
+# The one-hour setback will go into effect throughout most of Ontario,
+# except in areas like Windsor which remains on standard time all year.
+#
+# Windsor is, of course, a lot larger than Nipigon.
+#
+# I only came across this incidentally. I don't know if Windsor began
+# observing DST when Detroit did, or in 1974, or on some other date.
+#
+# By the way, the article continues by noting that:
+#
+# Some cities in the United States have pushed the deadline back
+# three weeks and will change over from daylight saving in October.

+# A list of the places in Canada using daylight saving time would
+# require yearly revision. From information kindly furnished by
+# the provincial governments and by the postmasters in many cities
+# and towns, it is found that the following places used daylight sav-
+# ing in 1930. The information for the province of Quebec is definite,
+# for the other provinces only approximate:
+#
+# Province Daylight saving time used
+# Prince Edward Island Not used.
+# Nova Scotia In Halifax only.
+# New Brunswick In St. John only.
+# Quebec In the following places:
+# Montreal Lachine
+# Quebec Mont-Royal
+# Levis Iberville
+# St. Lambert Cap de la Madeleine
+# Verdun Loretteville
+# Westmount Richmond
+# Outremont St. Jerome
+# Longueuil Greenfield Park
+# Arvida Waterloo
+# Chambly-Canton Beaulieu
+# Melbourne La Tuque
+# St. Theophile Buckingham
+# Ontario Used generally in the cities and towns along
+# the southerly part of the province. Not
+# used in the northwesterlhy part.
+# Manitoba Not used.
+# Saskatchewan In Regina only.
+# Alberta Not used.
+# British Columbia Not used.

+# With some exceptions, the use of daylight saving may be said to be limited
