As Canadians gear up for the April 28 election, they’ll vote in a freshly redrawn electoral map featuring 343 ridings—five more than last time. Pollsters say the updated boundaries could hand the Conservatives a subtle edge, though the changes won’t rewrite the race entirely.
Canada’s riding count jumped from 338 to 343, with three new seats in Alberta, one in British Columbia, and one in Ontario. Only 48 of the old ridings survived unscathed, while others saw boundaries shift or vanish—like Toronto’s Don Valley East. The redraw, triggered by the 2021 census to reflect population growth, began in October 2021 under Elections Canada’s nonpartisan mandate.
Dan Arnold, Pollara’s chief strategy officer and a former Trudeau pollster, sees a Conservative lean. “They’re stronger in fast-growing areas like Alberta, and that’s where the map reflects reality,” he said. Three new Alberta seats and one in B.C.’s interior—both Tory strongholds—bolster their odds. But Arnold cautions the impact is “minimal” compared to bigger forces like leadership changes or the “Trump factor.”
Philippe Fournier of 338Canada agrees the Conservatives gain a “small advantage” but calls the shifts “relatively minor.” He points to Quebec, where the Bloc Québécois could capitalize on an expanded Gaspésie—Les Îles-de-la-Madeleine riding, now merged with a Bloc-friendly zone. Liberal ex-minister Diane Lebouthillier, who barely won there last time, now faces an uphill fight. A new Bloc-leaning seat in Montreal’s northern suburbs adds to their edge.
In Saskatchewan, the redrawn Desnethé—Missinippi—Churchill River riding sheds a Conservative-heavy chunk, tilting it toward the Liberals’ First Nations base—though the Tories remain provincial favorites. Meanwhile, the NDP could stumble in northern Ontario, where Timmins grows trickier without retiring MP Charlie Angus anchoring the vote.
Arnold warns against overanalyzing old results on the new map. “People move, preferences shift—boundaries are just one piece of the puzzle,” he said. Toronto’s Liberal-held Don Valley East is gone, but Conservative-leaning suburbs gained seats—yet Liberal voters spilling into those areas could muddy the math.
The redraw has sparked friction. Liberal MP Jaime Battiste (Sydney-Victoria) slammed it as “unconstitutional,” eyeing a run in the new Sydney-Glace Bay riding alongside colleague Mike Kelloway (Cape Breton-Canso). Both claim the Liberal nod, but the party’s website lists no candidate for either riding as of Friday. In Toronto, Michael Coteau, whose Don Valley East seat vanished, called the process “flawed” in 2023; he’s now running in Scarborough–Woburn.
Fournier says full candidate lists won’t drop until late in the campaign. As of mid-March, the Conservatives lead with 275 of 343 nominees, followed by the NDP (230), Greens (208), Liberals (195), and Bloc Québécois (11 in Quebec). Parties are still scrambling to lock in contenders for winnable ridings.
Pollsters agree: the new map nudges the Conservatives ahead, especially in Alberta, but it’s no game-changer. With bigger electoral currents at play, the redrawn lines are just one twist in a high-stakes race.
