The off-road motor vehicle injury emergency visit rates have been increasing since 2018 in both Simcoe Muskoka and Ontario overall. This follows a significant decreasing trend from 2008 to 2018. The 2021 rate in Simcoe Muskoka is the highest it has been in more than a decade. This most recent increase was due mainly to an increase in ATV-related injuries, which increased by 40% in Simcoe Muskoka and 30% across Ontario since the start of the pandemic.

The male and female off-road motor vehicle injury emergency visit rates were approximately twice as high as the comparable provincial rates since 2003.
In 2020, snowmobile-related emergency visits among females in Simcoe Muskoka decreased by more than 40%, while visits among males only decreased by 15%. In 2021, snowmobile related emergency visits returned to the levels observed in 2019 for both males and females. In 2020, ATV-related emergency visits increased by approximately 30% for both males and females; however, in 2021 rates remained the same for females but increased by another 10% among males.

The male off-road motor vehicle injury emergency visit rates were more than the three-times higher than the female rates since 2003.
