The influx has strained resources in the seven-island Atlantic archipelago and pushed migration to the top of the political agenda in Spain, which along with Italy and Greece is a key entry point for migrants seeking a better life in Europe.
A total of 56,852 migrants entered Spain illegally last year, an 82.1 percent jump from 2022 and the most since 2018 when 64,298 migrants entered the country, according to provisional interior ministry figures.
The bulk of them, 39,910, arrived by boat in the Canaries after making the perilous crossing from Africa, an increase of 154.5 percent over last year and surpassing the record number set in 2006.
With controls tightening in the Mediterranean, the Canaries route has become a favorite for people fleeing poverty and conflict in Africa, mostly on overcrowded, barely seaworthy vessels.
More than 7,800 people died or went missing at sea en route to the archipelago between 2018 and 2022, according to Spanish NGO Caminando Fronteras, which helps migrant boats in distress and the families of those who have gone missing.
