Statistics Canada says police reported more than 90,000 impaired driving cases in 2011, about 3,000 more than in 2010.
The agency says the rate of impaired driving was 262 cases for every 100,000 people, up two per cent from 2010.
It was the fourth increase in five years, although before 2007, the impaired driving rate had been on a steady decline since the mid-1980s.
The report says there were 121 incidents of impaired driving causing death in 2011 and a further 839 incidents of impaired driving causing bodily harm.
However, the rates of impaired driving causing death and causing bodily harm per 100,000 population were the lowest in 25 years.
Young adults aged 20 to 24 recorded the highest impaired driving rates in 2011, based on the number of licensed drivers and rates then declined steadily with age.Report Typo/Error
