Justin Trudeau’s Liberal Party won the most seats in yesterday’s Canadian election but he lost his overall majority. The Conservatives won the popular vote but did not win enough seats to form a government. The Liberals are now likely to form a minority government, possibly with the help of the left-wing New Democratic Party (NDP).
So far the Canadian election maps that I have seen haven’t been very informative. In the last American and UK elections lots of election maps used arrows to show how votes had swung since the previous election. These arrow maps are great for visualizing how different parties have performed better or worse across the country since the last election (here’s an example from the U.S. midterms). With the Liberals losing their overall majority it would be interesting to see an arrow swing map of the Canadian election to see where the Liberals and Conservatives in particular lost and won vote share across Canada.
CBC’s Canada Votes 2019 includes a simple interactive map showing the result’s of yesterday’s election. The Globe and Mail have a very similar map on their Election 2019 Results. On these maps electoral districts are simply colored to show the winning party. You can hover over individual districts on the CBC map to view the name of the winning candidate and by how many votes that they defeated their nearest challenger. Either of these maps could have easily been made more informative simply by shading the districts by the percentage of votes won by the winning candidate. This would at least have provided an overview of where support for the different parties was stronger or weaker across the country.
As they are these maps do provide some insight into some of the major stories of this election. The light blue colored districts in Quebec highlight the surge of the Bloc Québécois. They tripled their party’s seat count, compared to the 2015 election (mostly at the expense of the Liberals), and have become the third largest party after the Liberals and Conservatives. Elsewhere, in the western Prairie provinces, the Conservatives swept the board and the Liberals failed to win a single seat in the area.
Global News has a similar map, which simply colors each electoral district by the color of the winning party. The Global News map does include a button for an ‘equal area’ view. However this equal area view isn’t a map but simply a series of colored squares representing each electoral riding. These square are at least organized by province. However they would work far better organized into a cartogram.
Luke Andrews’ Electoral Cartogram of Canada holds out the promise of a cartogram with an equal area view of the Canadian election. On this 2015 election map each electoral district is the same size. This cartogram view provide a more easy to understand overview of the seats won by each party than provided by a more straightforward geographical map. Unfortunately (at the time of writing) Luke hasn’t yet added the 2019 votes. The map does have a ‘2019’ button so I suspect the results will be added soon.
This is obviously very early after the result of the Canadian election. I do suspect that in the next few weeks we will see the release of far more interesting and informative maps of the 2019 Canadian Election. At least I hope we do.
