2019-2022 Canadian tornado warning accuracy was 23-35% according to the Northern Tornadoes Project, prompting Environment Canada to consider new models and systems for improvement.

Canada's tornado prediction accuracy needs improvement, with only 23-35% of tornadoes preceded by warnings between 2019-2022, according to the Northern Tornadoes Project at Western University. Researchers suggest improved training for forecasters to swiftly assess unpredictable weather patterns, better use of radar and satellite data, and increased investment in detection equipment and meteorologist training. Environment Canada plans to test a US tornado-predicting model, introduce a color-coded alert system, and use more flexible polygon zones for alerts to improve accuracy.
