The person who finds the most errors will
So what is and is not an error? Remember that the "official and final" maps only go up once all the errors are caught. Hence there are some minor discrepancies that are not errors, they are just a symptom of me not being 100% finished.
Not an Error: Various islands within a riding have the wrong colour.
Error: A riding has the wrong colour (IE, showing the wrong party has won).
Not an Error: The winning party is shown in a different shade than the legend.
Error: A Bloc seat is shown as a Tory seat, or vice versa.
Not an Error: Your map says "Montreal" but it includes Laval too.
Error: A riding is mis-labled either with the wrong number or name.
Not an Error: Two parts of the same riding have the same identifying number.
Error: Two separate and different ridings have the same identifying number.
Finding ridings that had their name change midway from a boundary change, and noting the date of said change.
