In 2018, a systematic review of provincial obesity statistics from Statistics Canada showed that 26.8% of adult Canadians meet the height and weight classifications to be considered obese. Considering the proportion of the population that is also overweight, which is 36.3%, the total shows 63.1% of adult Canadians face increased health risks due to excess weight.
