Seats were 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][4] After legal amendments in 2018 and 2022, fixed-term mandates were abolished, instead allowing the term of the Parliament of the Canary Islands to expire after an early dissolution.

[1][4][5] The president had the prerogative to dissolve the Parliament of the Canary Islands and call a snap election, provided that no motion of no confidence was in process and that dissolution did not occur before one year had elapsed since the previous one.
