[1] Voting for the Parliament is on the basis of universal suffrage, which comprises all nationals over 18 years of age, registered in the Canary Islands and in full enjoyment of their political rights.

The 70 members of the Parliament of the Canary Islands are elected using the D'Hondt method and a closed list proportional representation, with an electoral threshold of 15 percent of valid votes—which includes blank ballots—being applied in each constituency.

Seats are allocated to constituencies, corresponding to the islands of El Hierro, Fuerteventura, Gran Canaria, La Gomera, La Palma, Lanzarote and Tenerife, as well as an additional constituency comprising the whole archipelago, with each being allocated a fixed number of seats:[1][2] The term of the Parliament of the Canary Islands expires four years after the date of its previous election, unless it is dissolved earlier.

[1][2][3] The president has the prerogative to dissolve the Parliament of the Canary Islands and call a snap election, provided that no motion of no confidence is in process and that dissolution does not occur before one year has elapsed since the previous one.

The highest percentage figure in each polling survey is displayed with its background shaded in the leading party's colour.
