An overall map showing the complete picture of the time zones would be very helpful. Also, a detail map of each of the time zones would be a good presentation at each of the sub-headings. Just some thoughts on the article. HJKeats 17:01, 8 March 2006 (UTC)

Requesting a map which would replace this and be clearer. RJFJR 16:59, 12 March 2006 (UTC)

The existing map also has an overlap problem. The Atlantic Timezone is shown as AST = UTC-4 and ADT = UTC-3. Part of that area is the Newfoundland timezone, UTC-3:30 in winter and UTC-2:30 in summer.

The problem is that the two timezones, AST/ADT and NST/NDT are shown in the same exact color.

I've found maps that show Standard and Daylight Savings timezone boundaries as two separate maps. These are significantly better maps than the current one. I'm in the process of checking to see if they can be used freely. Ge0nk (talk) 23:15, 5 June 2014 (UTC)


Suggest rename Timezones in Canada. Peter Grey 07:54, 9 March 2006 (UTC)

The sentence "Canada is divided into six time zones and ranks sixth among countries with respect to number of time zones, after France (twelve), Russia (eleven), the United States (nine), Australia (nine) and the United Kingdom (eight)." is (a) misleading and (b) incorrect.

Someone is probably trying to say that the United Kingdom AND the British Overseas Territories have eight timezones between them, but this is not explained or clarified.

The B.O.T. are not part of the UK ( ) It is likely that the other countries are similarily defined to be seperate from their overseas territories. states Russia has eleven time zones, including Kaliningrad on the Baltic Sea. France also has eleven time zones including those of France, French Guiana and numerous islands, inhabited and uninhabited. The United States has ten time zones (nine official plus that for Wake Island and its Antarctic stations). Australia has nine time zones (one unofficial and three official on the mainland plus four for its territories and one more for an Antarctic station not included in other time zones). The United Kingdom has eight time zones for itself and its overseas territories. Canada has six official time zones. —Preceding unsigned comment added by (talk) 18:31, 30 March 2009 (UTC)

I should remove United Kingdom, in fact, I may remove the entire paragraph for being original research. — RVJ (talk) 22:20, 22 February 2010 (UTC)

Start Date section[edit]

Instead of listing the dates they enacted legislation adopting the US dates, just list the dates their laws currently call for it to be in 2007. (It doesn't matter much what day they adopt the change since the effective date wouldn't be until that start date of DST.) Jon 16:28, 16 June 2006 (UTC)

What does that mean?[edit]

Regarding the section Time in Canada#Daylight saving time, it says "Saskatchewan - presumed defacto authorization coincident with Alberta and Manitoba," in regards to the USA's change in DST observance period.

What does that mean? We haven't observed DST here as long as I've been alive—so how could we authorise a change in the DST hours? This very page says DST is illegal here in Saskatchewan... odd. BigNate37(T) 01:32, 28 November 2006 (UTC)

I'm not the one who put in that passage, but I assumed it was referring to the parts of Saskatchewan that do have DST, namely the region from Lloydminster to Maidstone and Creighton (near Flin Flon). Indefatigable 18:46, 28 November 2006 (UTC)
I could see that being the rationale. I guess I don't really think of those DST-rebels when I consider the province in terms of timezone. BigNate37(T) 19:05, 28 November 2006 (UTC)
It definately needs reworded. Something like "parts that have historically observed DST near Alberta & Mantioba are presumed to be authorized to have the start & end dates the same as Alberta & Mantioba." Jon 17:11, 19 January 2007 (UTC)

I saw the reference to Daylight Savings Time being illegal in Saskatchewan, and I had to post a correction. Chapter 85 of the Statutes of Saskatchewan, 1966 (a.k.a. The Time Act, 1966) effectively says that the entire province has been on permanent Daylight Savings time since the Spring of that year. If the United States chooses to lengthen the amount of time they are on DST, I say "Welcome! Bring a couple of more months and stay the whole year." Just note that Saskatchewan is that little rectangele of CST that sticks into the MST. Can it get more obviouse than that? Faced with all the facts, I will still encounter people who say "Hyuck. You don't know how to change your watch."

Adoption of North American standard for DST[edit]

According to this article by the NRC, there is already some adoption of the standard, though it seems unclear on details:

So, what is this statement saying? That in 2007 all of Canada adopts this system, or that for those provinces that have adopted this system, this is how it works starting in 2007? Mindmatrix 19:16, 4 September 2007 (UTC)

Section with unclear purpose[edit]

The section "TZ zones" as it currently stands is unclear - it needs an explanation that I cannot provide. I don't know what "Goose_Bay Atlantic Time" refers to. PKT(alk) 17:17, 15 April 2009 (UTC)

Rank for number of time zones changed[edit]

Where does this information come from? no reference or real explanation. From the main Time Zone#Additional Information page

But this isn't cited either.

1965 Double Daylight Time[edit]

The NWT and Yukon territories were on double daylight time in 1965. This is unusual as neither territory was on daylight time previously, except for war time. Any wikipedians know why this was done then? I'm guessing it was unpopular and somewhat pointless that far north in the summer. Skywayman (talk) 07:19, 24 December 2009 (UTC)

This article[edit]

[1] claims that most time zone "quirks" are the result of residents of certain areas unofficially not following the time zone officially applicable. Should this not be pointed out in the article? (talk) 10:30, 31 March 2010 (UTC)

The article certainly requires expansion. Many of the links included at the end of the article should be used as references instead, including the one you mention. Mindmatrix 14:41, 31 March 2010 (UTC)

NAO vs CIA??[edit]

The section on Atlantic Time gives two different descriptions for the part of Quebec in that time zone, with the notations NAO and CIA, but with no explanation for what those notations mean. I'm guessing that one is de jure and the other de facto, but that's just a guess. Can someone clarify that bit? Lincmad (talk) 06:17, 6 February 2011 (UTC)


I found the layout of the listing very confusing as to what areas do/don't observe DST, so I reworked it from scratch, listing for each time zone first the areas that do not, then the areas that do observe DST. (I put them in that order so that they flow more naturally from west to east, since, for example, PDT and MST are the same.) I also removed the erroneous reference to Tungsten, NWT, as being in PST with no DST; that was clearly wrong, since that would put a tiny town of fewer than 200 people on the Yukon/NWT border effectively in Alaska Daylight Time in the summer. The new format could probably still use some more polish, but I do think it's an improvement. Lincmad (talk) 08:59, 6 February 2011 (UTC)

Southeastern B.C.[edit]

The time zone map in the article is great, but there are a few inaccuracies that I have noticed.

Southeastern B.C. uses Mountain Standard/Daylight Time, but the map currently shows this region using Pacific Standard/Daylight Time. The map at the Atlas of Canada site shows the extent of this region.

Also, the Lloydminster region that uses Mountain Standard/Daylight Time is larger than indicated on the current version. Indefatigable (talk) 16:59, 8 November 2011 (UTC)

I just came on here as well noticing that the map is incorrect in regards to Southeastern BC being on mountain time. I would be happy to edit the image but I don't know how to upload the edited image to replace this image once I'm done. If someone could give me a link with instructions, I'll go ahead and do it. I couldn't find any information about how to do it. Thanks. Air.light (talk) 06:02, 24 November 2011 (UTC)

I the creator of the map, have updated these changes mentioned, and will gladly fix any other inaccuracies on any of my maps, just contact me on my talk page, and the problems will be solved. – Phoenix B 1of3 (talk) 18:26, 24 November 2011 (UTC)

Daylight saving time[edit]

No. Canada was not the first place to adopt Summer time. Shackleton's expedition adopted it on 1915-09-26. "South", Chapter IV. They were at some place, albeit adrift there. (talk) 21:50, 27 May 2015 (UTC)
