No!

Explanation:

The purpose of #"DNA ligase"# is to join the okazaki fragments that are manufactured at lagging strand of replication fork. While at leading strand, the nucleotides are added continuously to the growing #3^'# end. So it doesn't have any okazaki fragments, hence it doesn't need #"DNA ligase"# .
