Monterrey reach Mexican final
In the final, Monterrey will meet Cruz Azul who went through on Saturday with a 2-1 victory over Morelia in the second leg of their semi-final having drawn the first leg 0-0.
Monterrey will be looking for their third league title and Cruz Azul their first since 1997.
The onus was on Toluca to fight back from their 2-0 defeat in the first leg in midweek but the closest they came to scoring for an hour was a shot by Brazilian-born forward Antonio Naelson that hit the post.
Monterrey took the lead in the 72nd minute when Abraham Carreno stabbed the ball home after Toluca keeper Alfredo Talavera dropped a cross from Ecuador's Walter Ayovi.
Toluca equalised through Isaac Brisuela following a poor clearance by the Monterrey defence.
