Yes, polar regions are reliably colder than equatorial regions. Lytton, BC hit the temperature you cite for one day on Tuesday, June 29, 2021. That's a sign of warming, and we should expect more warm days than in the past at any given lattitude. But it is not evidence against the general case that polar regions have colder climates than equatorial regions.

Here's a citation demonstrating that over the last 95 million years if you need one: https://www.pnas.org/doi/10.1073/pnas.2111332119
