• Source: List of Canadian tornadoes in 2023

This page documents all tornadoes confirmed by Environment Canada and the University of Western Ontario's Northern Tornadoes Project (NTP) in Canada throughout 2023. Based on statistical modelling by Sills et al. (2012), an average of 230 tornadoes likely occur across the country each year; however, only 61 of these are actually documented annually based on 1980–2009 averages. This makes Canada the second-most active country in the world for tornadoes. The majority of confirmed events occur in the more densely populated areas of southern Canada, where people are around to report them. In Alberta specifically, meteorologists estimated that 30–50 percent of tornadoes that actually occur go unreported, with NTP executive director David Sills stating, "we just don't get reports from the moose." In an attempt to better document the nation's tornadoes, the NTP was founded in 2017 as a joint venture by the University of Western Ontario and ImpactWX. Their initial scope was to catalogue previously unrecognized tornadoes in densely forested areas across Ontario and Quebec; however, this later expanded to tornadoes nationwide in 2019.
The year started slowly, possibly due to thunderstorm activity being suppressed by smoke from record-breaking wildfires. The first tornado of 2023 occurred on May 11 in Alberta while the strongest was an EF4 tornado on July 1, also in Alberta. The most active day of the year was an outbreak of 10 EF0 tornadoes on June 14 in rural areas of Alberta.
