If you do the math and read between the lines (amalgamating "not interested," "didn't like candidates/issues," and "forgot"), this suggests that almost 40% or 3 million voters didn't vote because they were uninterested.
Some interesting differences across Canada emerge in the Statscan analysis:
- Lack of interest as a reason for not voting was highest in Quebec;
- Lack of interest didn't seem to differ across age groups;
- Lack of interest was lower among voters with university education;
- Among immigrants with Canadian citizenship who didn't vote, only 13% cited lack of interest.
