In the first full day of campaigning in the Presidential Election, the three candidates will be canvassing in Dublin, Laois, and Limerick.
Independent candidate Catherine Connolly, who is backed by the left-leaning parties in the Oireachtas, will attend a meeting of the Dáil Public Accounts Committee this morning in her capacity as a TD for Galway West.
Afterwards, and as a presidential candidate, she will be campaigning in the capital, including at a rally in Harold's Cross this evening.
The Fine Gael candidate Heather Humphreys will start her campaign today in Laois, with a lunchtime canvass in Portlaoise.
Later, she will be canvassing in Limerick City before attending a Fine Gael rally in Patrickswell.
Earlier, Ms Humphreys said housing supply is "the biggest challenge" facing the country and "very tough", but stopped short of agreeing with outgoing President Michael D Higgins that it has become a "disaster".
The Fianna Fáil candidate Jim Gavin will be in the capital this morning, with a canvass in Blackrock and Dún Laoghaire.
He also will be joined by party colleagues at other campaign events in south Dublin.
Barrister Maria Steen failed to secure enough support to join the race, securing 18 Oireachtas nominations when 20 was required.
After her campaign ended yesterday morning, Ms Steen told the media that "rarely has the political consensus seemed more oppressive or detached from the public's wishes."
However, Taoiseach Micheál Martin rejected suggestions that the failure of Ms Steen to secure a nomination was "anti-democratic".
Voting takes place on 24 October. It is the smallest field in a Presidential Election since 1990.
