Opinion polling for the 45th Canadian federal election by constituency

Various polling organizations have conducted opinion polling in specific ridings in the lead up to the 45th Canadian federal election. The results of publicized opinion polling for individual constituencies are detailed in this article.

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.
