Patrice, If you want the short answer: we are still waiting to hear from Yukon, Nunavut, Newfoundland, and Saskatchewan. Before you write back and claim that Saskatchewan does not observe daylight time, please read the detail below. The other provinces and territories have either passed (or committed to pass) new legislation which will extend daylight time by four weeks. Version 2006d of the Olson database was updated to reflect an assumption that all provinces and territories will eventually follow the US rules by extending daylight saving. Here is the gory detail: Province of British Columbia: YES. BC will follow US rules. I don't know what the status of the legislation is at this time. The change is documented under regulation 136/2006 but I can't find this regulation on line. ### News Release: http://www2.news.gov.bc.ca/news_releases_2005-2009/2006AG0014-000330.htm Province of Alberta: YES. Alberta will follow US rules. ### Daylight Saving Amendment Act: http://www.qp.gov.ab.ca/documents/Acts/2006CH03_UNPR.cfm?frm_isbn=0779744934 City of Lloydminster: Lloydminster is a cross-border city; it straddles the Alberta-Saskatchewan border. Time on both sides of the provincial is governed by the "Lloydminster Charter". No word yet if the charter will be updated. I think we can assume that the people of Lloydminster will continue the tradition of keeping the clocks in sync with Alberta regardless of whether or not the charter is updated. ### Here are two links to the charter: Lloydminster charter (Government of Alberta web site): http://www.qp.gov.ab.ca/Documents/REGS/1979_043.CFM Lloydminster charter (Government of Saskatchewan web site): http://www.qp.gov.sk.ca/documents/english/Statutes/Historical/lloydchr.pdf Province of Saskatchewan: I am not aware of any announcements or new legislation. Most of the province does not use daylight time. The Battle Creek which includes Lloydminster does observe daylight time. The portion of the Battle Creek region that falls outside of the Lloydminster city limits and on the east side of the provincial border is covered by the Saskatchewan Time Act. I think we can assume that everybody in Battle Creek region will keep the clocks in sync with Alberta regardless or whether or not the Saskatchewan Time Act is updated. ### The Saskatchewan time act which was last updated in 1996 is about 30 pages long and rather painful to read. Here is a link to the old act: http://www.qp.gov.sk.ca/documents/English/Statutes/Statutes/T14.pdf Province of Manitoba: YES. Manitoba will follow US rules. Note: Manitoba has traditionally changed the clock every fall at 3:00 a.m. As of 2006, the transition is to take place one hour earlier at 2:00 a.m. ### The Official Time Act: http://web2.gov.mb.ca/laws/statutes/ccsm/o030e.php Province of Ontario: YES. Ontario will follow US rules. ### Ontario regulation 111/06 made under the Time Act http://www.e-laws.gov.on.ca/DBLaws/Source/Regs/English/2006/R06111_e.htm Province of Quebec: YES. Quebec will follow US rules. ### Bill 2 Legal Time Act: http://www.assnat.qc.ca/eng/37legislature2/Projets-loi/Publics/06-a002.htm Province of New Brunswick: YES. New Brunswick will follow US rules. Note: New Brunswick has traditionally changed the clocks in the spring and fall at 12:01 a.m. As of 2007, the transition is to take place 119 minutes later at 2:00 a.m. This will eliminate the excitement of having the date roll backwards. Unfortunately it means a minor update is required to the Olson database. ### An Act to Amend the Time Definition Act: http://www.gnb.ca/0062/acts/BBA-2006/Chap-19.pdf Province of Nova Scotia: YES. Nova Scotia will follow the US rules. I don't know what the status of the legislation is at this time. ### News Release: http://www.gov.ns.ca/news/details.asp?id=20060425004 Province of Prince Edward Island: YES. P.E.I. will follow US rules. The new legislation is not law yet. It passed first reading on April 20. ### Bill No. 101, An Act to Amend the Time Uniformity Act http://www.assembly.pe.ca/bills/pdf_first/62/3/bill-101.pdf Province of Newfoundland and Labrador NO commitment yet (that I know of). The change is being considered. ### There is a reference to the issue in this government news release: http://www.releases.gov.nl.ca/releases/2006/mpa/0331n01.htm Yukon Territory: I have no evidence to suggest that the government has discussed the issue. ### Here is a link to the old daylight saving portion of the interpretation act which was last updated in 1987: http://www.gov.yk.ca/legislation/regs/oic1987_056.pdf Northwest Territories: YES. N.W.T will follow US rules. ### Whoever maintains the government web site does not seem to believe in bookmarks. To see the news release, click the following link and search for "Daylight Savings Time Change" Press the "Daylight Savings Time Change" link; it will fire off a popup using JavaScript. http://www.exec.gov.nt.ca/currentnews/currentPR.asp?mode=archive Nunavut: I have no evidence to suggest that the government has formally discussed the issue. The premier made an off the wall in August of 2005 saying that he did not want to touch the issue. Regardless, I expect the people of Nunavut won't want to be out of sync with the rest of the continent and the issue will have to be addressed.

Yes. Our current prediction is that they'll fall into line with the US.
Is there any update on what Canadian provinces will do?
Not to my knowledge, for time stamps after 1970 anyway.

This reference has some extra bits of information that prompted me to fill in one of our long list of TODO items, namely time in far east Quebec. The reference says that Quebec observes EST/EDT if you are west of 63 degrees West longitude, or are in "the territory of Municipalite regionale de comte de Minganie". As I understand it from http://atlas.nrcan.gc.ca/ and Wikipedia, this territory straddles the meridian in question. It also says that Quebec observes AST if you are "east of the meridian of 63 degrees West longitude" or "in the territory of the Listuguj reserve" (which is west of that meridian -- evidently this is an exception to the general EST/EDT rule); and that during summer you observe ADT if you are "in the Iles-de-la-Madeleine" or "in the territory of the Listuguj reserve".
From this we can deduce that if you are in Quebec east of 63 degrees W., and are not in the MRC Miganie, and are not in the Iles-de-la-Madeleine, and are not in the territory of the Listuguj reserve, then you observe AST all year. This matches information we already have from Matthews and Vincent (1998), and I just now confirmed this from a quite detailed web page from the Quebec department of justice <http://www.justice.gouv.qc.ca/english/publications/generale/temps-regl-1-a.h...>.
With all these seemingly authoritative defacto and dejure references, we should have a Zone for this AST-only region. The 2001 Census of Canada lists Blanc-Sablon (pop 1201) as the most populous in this region, so I will propose adding a new zone America/Blanc-Sablon for it. For lack of better historical info I'll suggest something like this: Zone America/Blanc-Sablon -3:48:28 - LMT 1884 -4:00 Canada A%sT 1970 -4:00 - AST Evidently the folks in Listuguj prefer to sync with New Brunswick, and I suspect they can use America/Moncton; similarly the folks in Les Iles-de-la-Madeleine prefer Prince Edward Island or Nova Scotia time and can use America/Halifax.
Paul, I agree, there should be a zone named Blanc-Sablon. I would suggest the following entry in the zonetab file: CA +5125-5708 America/Blanc-Sablon Atlantic Standard Time - Quebec - Lower North Shore Also, "E Quebec" should be pulled from the America/Halifax entry in the zonetab file. It won't be needed after the new zone is added. I don't think that Iles-de-la-Madeleine or the Listiguj I.R. are significant enough to require any mention in the zonetab file. For information on the Lower North Shore region follow this link: http://www.coastersassociation.com/tourism/main.html#Municipal I actually did some digging into this a few weeks ago but I had not posted anything because there is a lot of conflicting information about the time-of-day in this region of Quebec. All of the Internet time/temperature web sites indicate that Blanc-Sablon and the other Lower North Shore communities observe daylight time. Some sites place it in Eastern time, others place it in Atlantic time. Even the NRC "summer time zone map" indicates that the region uses daylight time in the summer. http://inms-ienm.nrc-cnrc.gc.ca/images/time_services_images/TZ01SE.pdf The only web site that seems to show the correct time is the Envionment Canada weather forcast site: http://www.weatheroffice.ec.gc.ca/city/pages/qc-163_metric_e.html Look specifically at the section labeled "Currently" which shows the time in AST (updated hourly on the hour). If it were up to me, I would also make some changes to the Newfoundland and Labrador entries in the zonetab file. With the current setup, "W Labrador" is tied to America/Halifax which changes times at 2:00am while "E Labrador" is tied to America/Goose_Bay which changes times at 12:01am. This is only a suggestion, don't shoot me if you don't like it: CA +4734-05243 America/St_Johns Newfoundland Time - Newfoundland & SE corner of Labrador CA +5320-06025 America/Goose_Bay Atlantic Time - Labrador (all places except SE corner) CA +4439-06336 America/Halifax Atlantic Time - Nova Scotia (most places) and PEI note: it is not necessary to state "Newfoundland Island" when refering to the island of Newfoundland. The name of the province changed a few years ago from "Newfoundland" to "Newfoundland and Labrador". "Newfoundland" means the island of Newfoundland. "Labrador" means Labrador. "Newfoundland and Labrador" refers to the provice which is comprised of Newfoundland + Labrador. -chris -----Original Message----- From: Paul Eggert [mailto:eggert@CS.UCLA.EDU] Sent: Tue 6/27/2006 4:09 AM To: tz@lecserver.nci.nih.gov Cc: patrice.scattolin@oracle.com Subject: Re: Canada timezones (2007) "Chris Walton" <Chris.Walton@telus.com> writes: Wow, thanks for all those references!

Thanks for mentioning these, along with the Newfoundland stuff. I'll make changes along those lines in zone.tab.
there is a lot of conflicting information about the time-of-day in this region of Quebec.
No kidding! I observed the same thing. But I think we're getting it right here.
Paul and others, Can we consider adding a Canadian zone for the Ontario community of Atikokan? There are several comments about Atikokan in the northamerica file but nobody has ever created a zone. Based on the Ontario Time Act, Atikokan is supposed to use CST/CDT. Atikokan does not follow the Time Act and instead remains on UTC-5 year round. I could not find any "authoritative" web sites on the subject, however there are hundreds of web sites that mention the fact that Atikokan does not observe daylight time. Some of the web sites correctly indicate that Atikokan stays on UTC-5 year-round. Other sites incorrectly place Atikokan on UTC-6 and even UTC-7. The Atikokan time practice is mentioned in the Canadian Geographic "Its's about TIME" article. This article is already referenced in the Olson northamerica file. http://www.canadiangeographic.ca/Magazine/SO98/geomap.asp There was an article published last year in Thunder Bay's "Chronicle Journal". This article mentions Atikokan's use of Standard Time year-round and it contains a quote from the mayor of Atikokan. http://64.233.161.104/search?q=cache:6cIRPHfvxRgJ:www.chroniclejournal.com/s... There are several references on the web (including the articles above) which refer to Atikokan being on (or adopting) "Central Time" in the summer. Here is another reference: http://www.fftimes.com/print_version.php/22129 I came to the conclusion that Atikokan residents belive that their time zone changes twice a year as a result of ignoring daylight saving. This would imply that Atikokan uses EST in the winter and CDT in the summer (both of which are the same as UTC-5). Currently, Environment Canada (which seems to get the time zones correct for every other corner of Canada) is indeed using CDT for Atikokan. http://www.weatheroffice.ec.gc.ca/city/pages/on-148_metric_e.html. I don't believe that the Olson database easily allows switching between CDT and EST without defining special rules for each year; I suppose we should simply create a zone that uses EST year-round; it would be better than not having any zone at all. I believe Atikokan has been using UTC-5 since 1997 but I don't know what it did before that. Are we allowed to assume that this practice has been observed since 1970? Zone America/Atikokan -6:06:30 - LMT 1884 -6:00 Canada C%sT 1970 -5:00 - EST # zone.tab entry: CA +4845-9137 America/Atikokan Eastern Standard Time - Atikokan, Ontario Supposedly Pickle Lake and Mishkeegogamang follow the same practice as Atikokan but I don't think they are significant enough to mention in the zone.tab file. -chris

Thanks for the detailed info and proposed patch. I'm inclined to take it, except that a transition on 1970-01-01 from CST to EST seems unlikely. Given all the other information you sent, a more plausible changeover time would be the spring 1973 transition. Shanks & Pottenger say that in 1973 Thunder Bay observed EST without DST (this was for a one-year period), much as Atiokokan does now. Possibly Atikokan switched to plain EST at about the same time as Thunder Bay, and then liked it so much that they never changed thereafter. So if we incorporate the older Shanks & Pottenger data, this would be more plausible: Zone America/Atikokan -6:06:28 - LMT 1895 -6:00 Canada C%sT 1940 Sep 29 -6:00 1:00 CDT 1942 Feb 9 2:00s -6:00 Canada C%sT 1973 Apr 29 2:00 -5:00 - EST
