Opinion polling for the 2019 Canadian federal election by constituency

Various polling organizations have been conducting opinion polling in specific ridings in the lead up to the 2019 Canadian federal election. The results of publicized opinion polling for individual constituencies are detailed in this article.

Opinion polls have been conducted from the months following the previous general election held in October 2015, and have increased in frequency leading up to the October 2019 general election.

Given the expense of polling individual constituencies, constituencies are usually only polled if they are of some particular interest, e.g. they are thought to be marginal or facing an impending by-election. The constituencies polled are not necessarily representative of a national average swing. Under the first-past-the-post electoral system the true marginal seats, by definition, will be decisive as to the outcome of the election.
