In the 2019 Canadian election the steep rise in the number of voters voting at advance polling continued to rise and totalled 4,840,300 voters or 26% of all voters in that election.
The popularity of early voting had a perverse effect in that it did not get the turnout rate back up to the 75% when most of the votes were cast on one day, Election Day.
In 1993 advance poll voting became available for all voters.
Before the change, in 1988, 500,000 voters voted at advance polls or 3.8%.
The numbers for 1993 are 633,000 early voters or 4.6%.
In 2014 the Fair Elections Act added a fourth day of advance polling.and in the next election, 2015, there were 3,657,415 early voters or 20.8%.
In 2018 the hours of advance polls were extended.
