I wonder if the reports of long lines in Spadina-Fort York in the fall federal election discouraged voters from going to the polls last week.
S-FY was also one of the more notorious victims of polling station/subdivision amalgamation last federal election. And of course, as of the 2018 provincial election, the province adopted "megapolls" (i.e. polling locations that once accomodated several polling subdivisions were now one single subdivision, not unlike how it's been done municipally since mega-amalgamation). And it sounds like some ridings reduced their polling subdivisions even *further* from '18, S-FY among them.
I do wonder if, in some subliminal way, that's worked to dumb things down and discourage electors, in part by making it more complicated for candidates to "reach" the electors and determine fine-grained nodes of support for present and future elections--and it's not *too* unlike certain US forms of "voter suppression" involving precinct amalgamation/reduction. (Though less "racialized" in the case of Ontario than in the States, it probably operates on behalf of Ford Nation-type "big and dumb" campaigning; while NDP-type forces have typically relied upon a finer-grained polling-station-by-polling-station approach).
And I'm sure there's probably *some* kind of thinking that envisages some kind of "post-polling-station" future for elections, perhaps involving virtual voting or whatever--in which case, we might not be able to determine *any* patterns of support other than riding-wide. (And I can imagine it being mainly forces on the right that'd much rather suppress "open data" such as polling results)
