Wallin, who is facing allegations of questionable expense claims, will not face another suspension vote unless another senator decides to bring forward a motion, the Senate said.
Wallin and fellow senators Mike Duffy and Patrick Brazeau saw their suspensions from the Senate end with the dissolution of the last Parliament.
The incoming Liberal majority government will open Parliament with a speech from the throne in December, as CBC reported earlier this week.
Brazeau and Duffy, who have criminal charges pending against them, will be on leaves of absence with pay until their cases are resolved by the courts, said Nancy Durning, a spokeswoman for the Senate, in an email to CBC News.
"They cannot attend Senate and committee meetings except once at the second session to maintain their qualification with respect to attendance."
The Senate is still clawing back Brazeau's salary to repay nearly $50,000 in disallowed housing expense claims.
Brazeau still faces a criminal trial for fraud and breach of trust arising from his Senate expenses, scheduled to take place in March 2016.
Duffy repaid his disputed Senate expense claims with a $90,000 cheque given to him by Nigel Wright, Prime Minister Stephen Harper's former chief of staff.
He has pleaded not guilty to 31 charges of fraud, breach of trust and bribery related to expenses he claimed in 2013 as a senator.
The fourth phase of Duffy's trial will resume on Nov. 18.
In an interview with CBC News chief correspondent Peter Mansbridge in 2013, Wallin apologized for mistakes she may have made when filing travel claims.
She has since paid back a total of $154,191.
