He actualized the first environmental ministry (Trudeau 156) and maintained his position up to 1979 then inherit it again in 1980 until 1984.

Actualized means to achieve a long standing goal that has been hard to establish because of certain blockades.
So, the sentence says that this person was finally able to open a long planned environmental ministry for the first time. He was named the head (I assume) from the year it opened until 1979 and then became the head of the ministry again from 1980-1984.
