Sorry to spoil the fun but Nanday Parakeet is definitely NOT on Cat C of the Spanish list, which includes the Canaries. A new list was actually released just a few weeks ago.
The only country you can count it in is Israel, though I haven't heard of any reports in recent years.

What about this: Checklist of the Birds of the Canary Islands 2018 - I do not know the local relationships, but : Sociedad Ornitologica Canaria seems like a relevant body and their list has the standard categorization.
