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

# From Mark Brader (2010-03-06):

# # 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.

# 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
