Prince Edward Island remains as one of only two jurisdictions in Canada without a full slate of senators but Prime Minister Paul Martin, the man who makes the appointments, isn't saying when that post will be filled.

P.E.I. has been without a full slate of senators since Eileen Rossiter, a Progressive Conservative appointment, retired in July 2004.

Martin said the P.E.I. senator will be appointed in "due course."

"There were a lot of places where there were a shortage of senators from those areas," Martin said in an interview with The Guardian Thursday. Obviously, within P.E.I. you have a number of senators."

But Martin said he won't delay in making the appointment. He said it will be filled "as soon as feasible."

Martin also wouldn't hint who might get the job, which comes with guaranteed employment until the age of 75 and an annual salary of $119,300 plus benefit.

There is speculation former Summerside businessman Michael Schurman, former Charlottetown city councillor Frank Zakem and former Liberal Premier Keith Milligan may be in the running.

P.E.I. has four Senate seats. The other three are filled by Catherine Callbeck, a former Liberal premier; Libbe Hubley, a former Liberal MLA; and Percy Downe, who was chief of staff for Prime Minister Jean Chretien.

On Wednesday, Martin appointed Sandra Lovelace Nicholas, a Maliseet from the Tobique First Nation in New Brunswick to the upper chamber. Lovelace Nicholas, born in 1948, rose to international prominence in 1977 when she petitioned the United Nations over Canada's discriminatory policies toward native women and children.

Her campaign eventually bore fruit in 1985 when Ottawa agreed to abolish a 116-year-old clause in the Indian Act that stripped women of their Indian status if they married non-aboriginal men.

Martin has appointed 15 senators - 10 of them Liberals - in the past six months after allowing 16 vacancies to open during his first year as prime minister. The other seat to be filled in the 105-seat chamber is in New Brunswick.
