Liberal Leader Dwight Ball says he wants Labrador's four seats to be protected, given its vast geography.
Ball is also calling on the government to allow the electoral boundary commission a range of six to 10 seats to eliminate.
Premier Paul Davis has said he wants the 48-seat legislature to be reduced by 10 seats.
Ball says he also wants amendments that would ensure that the electoral boundaries would not change for this year's election if the commission can't complete its work in 120 days, adding that he does not support delaying the election until next year.
His comments came as the legislature opened Monday to discuss the government's plan to amend the Electoral Boundaries Act.
