The results of publicised opinion polling for individual constituencies are detailed in this article.
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.
A total of 204 polls in 107 ridings across 9 provinces and 1 territory were conducted.
