1332# Quebec
1333
1334# From Paul Eggert (2013-08-30):
1335# Since 1970 most of Quebec has been like Toronto.
1336# However, because earlier versions of the tz database mistakenly relied on data
1337# from Shanks & Pottenger saying that Quebec differed from Ontario after 1970,
1338# a separate entry was created for most of Quebec. We're loath to lose
1339# its pre-1970 info, even though the tz database is normally limited to
1340# zones that differ after 1970, so keep this otherwise out-of-scope entry.
1341
1334# From Paul Eggert (2015-03-24):
1335# See America/Toronto for most of Quebec, including Montreal.
1336#
1342# Matthews and Vincent (1998) also write that Quebec east of the -63
1343# meridian is supposed to observe AST, but residents as far east as
1344# Natashquan use EST/EDT, and residents east of Natashquan use AST.
1345# The Quebec department of justice writes in
1346# "The situation in Minganie and Basse-C��te-Nord"
1347# http://www.justice.gouv.qc.ca/english/publications/generale/temps-minganie-a.htm
1348# that the coastal strip from just east of Natashquan to Blanc-Sablon
1349# observes Atlantic standard time all year round.
1350# http://www.assnat.qc.ca/Media/Process.aspx?MediaId=ANQ.Vigie.Bll.DocumentGenerique_8845en
1351# says this common practice was codified into law as of 2007.
1352# For lack of better info, guess this practice began around 1970, contra to
1353# Shanks & Pottenger who have this region observing AST/ADT.
