Hermoso played a key role in her side’s 2023 World Cup success – beating England in the final – and her three goals and performances helped her win the Silver Ball at the tournament.
But she then became the centre of controversy when the then-RFEF president Luis Rubiales kissed her on the lips without her consent as she went to collect her winner’s medal in Sydney.
Despite resisting calls to resign, Rubiales was forced to step down from his role and fined 10,800 euros (£8,942) as Spain’s High Court found him guilty of sexual assault.
Hermoso subsequently played a part in Spain’s qualification for Euro 2025 and helped them win a bronze medal at the Paris Olympics in 2024.
But after the appearance against Canada, Tome said she did not select the forward due to her performances for her Mexican club.
“I understand that she is angry for not being called up when she feel she has to be,” said Tome.
“I try to be respectful, I have always been. I have given my arguments, I have a clear conscience and I know that I have worked professionally. We have followed Jenni in her team with the help of information from her coaches.”
Leon, 30, returns after last playing at Euro 2022, where Spain were beaten by the Lionesses in the quarter-finals.
She was then one of 15 players who asked not to be called up amid a dispute over working conditions and the conduct of then-head coach Jorge Vilda.
While most of those players on strike returned after Vilda was replaced by his former assistant Tome in September 2023 following the Rubiales scandal, Leon did not.
