Canada is going through some other unhealthy wildfire season, with burning forests sending smoke plumes around the provinces and into the U.S. once more. The tempo of the 2025 fires is paying homage to the record-breaking 2023 wildfire season, which uncovered hundreds of thousands of folks in North The us to hazardous smoke ranges.
