Short summary

This paper investigates the vertical impacts of the anomalous 2023 Canadian wildfire season using multiple satellite instruments. Our results highlight that despite a record-breaking area burned, only a small amount of smoke managed to enter the stratosphere. This shows that the conditions for deep convection were rarely met in the 2023 wildfire season, suggesting that even a massive area burned is not necessarily an indicator of stratospheric perturbations.
