The Liberals, Tories and Greens have all fallen slightly in Mainstreet Research’s latest national polling numbers, while the NDP, Bloc Québécois and People’s Party enjoyed moderate bumps in support.

These latest survey numbers, though, only capture roughly one day of polling since the emergence of photos and videos of Liberal leader Justin Trudeau wearing blackface and brownface.

Overall, the Liberals are still leading the pack with 36.8 per cent of support among leaning and decided voters, compared to 34.2 for the Conservatives, 10.1 for the NDP, 9.8 for the Greens, 4.7 for the Bloc, 3.7 for the People’s Party and 0.7 for the unspecified other party option.

These numbers come from a telephone survey of 2,087 Canadian voters conducted between Sept. 17 and 19. As a daily tracking poll, it’s consistently updated to provide a snapshot of voter preferences over the past three days. According to Mainstreet, the margin of error for the results published Friday is plus or minus 2.14 percentage points.

The first media reports unearthing photos and videos of Liberal leader Justin Trudeau wearing blackface and brownface were published on the evening of Sept. 18.
