Thanks to Oscar for the input. Chris Walton has obviously put a big effort into the documentation site (page) you mention. However, my problem remains: how big is for instance the Nipigon timezone? We know that the center of Nipigon city must lie in the timezone, and the timezone must be equal to or (most certainly) less than the Thunder Bay District that contains Nipigon city http://en.wikipedia.org/wiki/Thunder_Bay_District%2C_Ontario but this page is of little help: http://en.wikipedia.org/wiki/Nipigon%2C_Ontario so I made my own little map of the Nipigon timezone, as good a guess as any I imagine, just painting an arbitrary circle around Nipigon city, from a map fraction taken from http://www.canadiangeographic.ca . I'm attaching that in the file Nipigon.zip which contains an image file Nipigon.jpg Can anyone guess better than that? I certainly hope so, because I'm not very happy with my guess, but I don't know how to improve it. Perhaps I could try to pin-point bigger cities surrounding Nipigon, for which we can assume they did not join the Nipigon timezone, and then make a border that goes midways between these cities and Nipigon itself. That would be a bit more reasonable approach. If anyone can help me, I would really appreciate it.

As a side-question, I'm trying to determine a meaningful area for the timezones Atikokan and Nipigon, it seems to me that they would be small, like a US county for instance, but I can't find anything about it. It seems they must be within the larger areas Rainy River district and Thunder Bay district, but how would it look on a map?
Chris Walton put a lot of effort in researching the Canada situation. <http://www3.sympatico.ca/c.walton/canada_dst.html> Very detailed! And then there is of course the Matthews-Vincent 1998 article everybody refers to. It is quite possible that there is simply no more detail available....
