We’re at work on Ontario 2018, to be added to Prime Minister Infinity – Canada.
Anyone who wants to work on an Ontario campaign is welcome to use the map, which is based on the 2013 redistricting but should be good as a basis for historical campaigns as well.

Here’s an example of the map in action (colours are not correct for Ontario 2018, included to show the regions).
