Voting was on the basis of universal suffrage in a secret ballot. Only lists polling above 30% of the total vote in each district or above 6% in all of the community (which include blank ballots—for none of the above) were entitled to enter the seat distribution.
Poll results are listed in the table below in reverse chronological order, showing the most recent first. The highest percentage figure in each polling survey is displayed in bold, and the background shaded in the leading party's colour. In the instance that there is a tie, then no figure is shaded. The lead column on the right shows the percentage-point difference between the two parties with the highest figures. Poll results use the date the survey's fieldwork was done, as opposed to the date of publication. However, if such date is unknown, the date of publication will be given instead.
Opinion polls showing seat projections are displayed in the table below. The highest seat figures in each polling survey have their background shaded in the leading party's colour. In the instance that there is a tie, then no figure is shaded. 31 seats were required for an absolute majority in the Parliament of Canarias.

^This survey shows its poll results projected over candidacy votes (that is, votes going for political parties, excluding blank ballots). The vote percentage in the official election is calculated including blank ballots into the estimation. In order to obtain data comparable to both the official results as well as those of other surveys, a rule of three has been applied to the survey projections, with the results of the calculation being shown instead.
^This poll provides data ranges and/or approximations. In order to simplify, the average of these data is given.
