Show historical "sequence" on a maphistorical map

My first impulse would be to show the different provinces in a progression of colours that looks intuitive: something like darkest to lightest, or most saturated to least saturated. And then just add the date under each province name. This would bypass the need for a graph.

I concur with that recommendation, however in the interests of clean design, you might think about using inner glow on the boundaries a la National Geographic style instead of solid polygon fills.

You know what would be nice if all the useful articles and tutorial data on this site would be listed under a table of contents so that users whether they are members or not would have easier access to the information on cartographic techniques ala the information library. Just an idea with the mention of the inner glow function hasecbinusr mentioned here, though even in this case the different software packages must be accounted for. While we are at it, should the territories be under a different shade of the same colour because they are not technically provinces?

This is a good point. I could see the provinces being shades of one color and the territories being shades of a different color.

I'm in the process of writing a tutorial manual for cartography in Illustrator for a client. I didn't realize there would be an interest on here for something like that, but I'd be happy to post them here as they're complete. If you're interested in specific things, send me a message and I'll add it to my list if it's not already there.

I second Charles's thoughts, but two other ideas:
First, the date alone is probably a clear enough indicator. A sequential array of colours is not inherently meaningful to the user, so you're making them do work for only 14 data points.
Second, this is a job for small multiples. Have eight tiny little maps, each showing Canada as it existed that year, arrayed along a simple timeline to the right of or below the main map.

Based on you comments and suggestions, this is what I have so far:
1. Provinces and territories with date of entry in the Confederation (the designer will choose how differentiate the two types).
2. National Geographic-style strokes with a "proportional" color ramp based on date of entry.

3. A graph because I had an idea I wanted to try...

I think Dennis' idea of the multiples is the way to go, if it's OK with your client. I have the 4th edition of the National Atlas of Canada, and that's exactly the way they did it (pages 85-86). You may have to go to a library to see it, or maybe there's a more recent version online, but it's worth a look.

I agree, I think the small multiples might be worth a try.
In the first graphic you posted, the color ramp is completely lost on me and I cannot distinguish any difference in the darker shades of red. This might be better executed with bins of closely spaced dates (perhaps four classes).
