The Grand Lodge of Ireland has approved to elevate this status by the Constitution of a Province in Sri Lanka. The ceremony to mark this occasion was held on the 16th June 2006 at the Victoria Masonic Temple, Colombo 3. Right Worshipful Brother Colonel Lau Kee Siong, Grand Inspector for South-East Asia was nominated by the Grand Lodge of Ireland to be the Presiding Officer, who conducted the ceremony with a team of Officers from Singapore. The Ceremony of the Constitution was followed by a Banquet at the Crystal Room at Hotel Taj Samudra, Colombo.

The Constitution of the Province in Sri Lanka was an epoch making day in the history of Irish Freemasonry in Sri Lanka. The incumbent Grand Inspector Right Worshipful Brother Colonel R. Harindran is the first Provincial Grand Master to be appointed to this high office.

Right Worshipful Brother Chandranath Mohan Wanigatunga was installed as the 2nd Provincial Grand Master by Right Worshipful Brother Colonel Ramalingam Harindran at the special communication being held to mark the 10th anniversary of the Provincial Grand Lodge of Sri Lanka. The historic celebration of this milestone was held on 25th June 2016 at Victoria Masonic Temple followed by a banquet at Grand Oriental Hotel, Colombo.

Charity is the hallmark of Freemasonry, and Irish Freemasons have been engaged on many projects of charity throughout the island. Schools, hospitals, day care centres have received donations, whilst public infrastructure projects such as bridges and roads in rural areas, have been funded by Irish Masons. With the Constitution of the Province, Irish Freemasons feel strengthened to do more for the needy in Sri Lanka.
