 # entry since our cutoff date of 1970, so we can move
 # America/Coral_Harbour to the 'backward' file.
 
+# From Mark Brader (2010-03-06):
+#
+# Currently the database has:
+#
+# # Ontario
+#
+# # 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.

+# It includes the text below (starting on page 57):
+#
+#   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
+# to those cities and towns lying between Quebec city and Windsor, Ont.
