1327# From Mark Brader (2010-03-06): 1328# 1329# Currently the database has: 1330# 1331# # Ontario 1332# 1333# # From Paul Eggert (2006-07-09): 1334# # Shanks & Pottenger write that since 1970 most of Ontario has been like 1335# # Toronto. 1336# # Thunder Bay skipped DST in 1973. 1337# # Many smaller locales did not observe peacetime DST until 1974; 1338# # Nipigon (EST) and Rainy River (CST) are the largest that we know of. 1339# 1340# In the (Toronto) Globe and Mail for Saturday, 1955-09-24, in the bottom 1341# right corner of page 1, it says that Toronto will return to standard 1342# time at 2 am Sunday morning (which agrees with the database), and that: 1343# 1344# The one-hour setback will go into effect throughout most of Ontario, 1345# except in areas like Windsor which remains on standard time all year. 1346# 1347# Windsor is, of course, a lot larger than Nipigon. 1348# 1349# I only came across this incidentally. I don't know if Windsor began 1350# observing DST when Detroit did, or in 1974, or on some other date. 1351# 1352# By the way, the article continues by noting that: 1353# 1354# Some cities in the United States have pushed the deadline back 1355# three weeks and will change over from daylight saving in October. 1356 1357# From Arthur David Olson (2010-07-17): 1358# 1359# "Standard Time and Time Zones in Canada" appeared in 1360# The Journal of The Royal Astronomical Society of Canada, 1361# volume 26, number 2 (February 1932) and, as of 2010-07-17, 1362# was available at 1363# <a href="http://adsabs.harvard.edu/full/1932JRASC..26...49S"> 1364# http://adsabs.harvard.edu/full/1932JRASC..26...49S 1365# </a> 1366# 1367# It includes the text below (starting on page 57): 1368# 1369# A list of the places in Canada using daylight saving time would 1370# require yearly revision. From information kindly furnished by 1371# the provincial governments and by the postmasters in many cities 1372# and towns, it is found that the following places used daylight sav- 1373# ing in 1930. The information for the province of Quebec is definite, 1374# for the other provinces only approximate: 1375# 1376# Province Daylight saving time used 1377# Prince Edward Island Not used. 1378# Nova Scotia In Halifax only. 1379# New Brunswick In St. John only. 1380# Quebec In the following places: 1381# Montreal Lachine 1382# Quebec Mont-Royal 1383# Levis Iberville 1384# St. Lambert Cap de la Madeleine 1385# Verdun Loretteville 1386# Westmount Richmond 1387# Outremont St. Jerome 1388# Longueuil Greenfield Park 1389# Arvida Waterloo 1390# Chambly-Canton Beaulieu 1391# Melbourne La Tuque 1392# St. Theophile Buckingham 1393# Ontario Used generally in the cities and towns along 1394# the southerly part of the province. Not 1395# used in the northwesterlhy part. 1396# Manitoba Not used. 1397# Saskatchewan In Regina only. 1398# Alberta Not used. 1399# British Columbia Not used. 1400# 1401# With some exceptions, the use of daylight saving may be said to be limited 1402# to those cities and towns lying between Quebec city and Windsor, Ont. 1403 |
