I don't know what canon means either, sorry.
So it wasn't the Bothans that got the plans Leia has at the beginning of Ep IV? Those ones were definitely for the first death star. Did they get the ones at the beginning of Episode 6 then?
The
Star Wars canon is what is officially regarded as "canonical", or officially part of a story, in the
Star Wars media franchise.
The official
Star Wars canon consists of the six released
Star Wars theatrical feature films, along with the
Star Wars animated film and television series
The Clone Wars and
Star Wars Rebels. The upcoming feature film
Star Wars: The Force Awakens (along with the untitled
Episode VIII and
Episode IX) will also be a part of the official canon.
[
On April 25, 2014, Lucasfilm and Disney revised the franchise's canon. They announced that the existing six films and
The Clone Warstelevision series are the "immovable objects" of
Star Wars storytelling. Previously published material has been relabeled under a "Legends" label, and future content will present a different vision of people, places and events after
Return of the Jedi. They also announced that all future
Star Wars stories will be connected, with guidance coming from the
Star Wars story group. Additionally, it was announced that the films of the sequel trilogy will not follow the same story as that of the Expanded Universe works taking place after the events of
Return of the Jedi.

No the first set of plans were stolen and captured piece by piece over years. The bothans stole the 2nd set of plans.
The Bothans were famously credited with stealing the
plans to the
second Death Star during the
Battle of Korriban, enabling the
Rebel Alliance to destroy the
battlestation.
