Tuscan Lodge in Newmarket was warranted on March 19, 1858

For the first one hundred years, meetings were held in rooms in various rental locations along main Street, including the old Era and Express Building ( now occupied by Roadhouse and Rose), the Widdifield Block (on the south-west corner of Botsford Street) and the Wesley Block (above the old National Trust offices).

The present Lodge building was the original Christian Church occupying the present site of the Christian Baptist Church at the top of the Main Street Hill. While the new church was being constructed, the small old buildimg was moved to its present location and sold to the British Templars (no connection to the present Masonic Knights Templar Order). It was subsequently sold to the Women's Christian Temperance Movement, from which the building was purchaced by Tuscan Lodge in 1957.

Extensive renovations were carried out including the addition of thirty feet to the rear of the building and the installation of a full basement. The old clapboard front portion of the structure was re-clad in brick, while the rear portion is solid brick. Much of the interior work was done by members of the Lodge who donated their time and professional talents. Many of the Lodge members at the time were employees of the Office Specialty Company. All of the furnishings inside the building were donated by members. The building was dedicated on December 5th, 1958 by the Grand Master of Canada, Most Worshipful Brother Harry L. Martyn.

The charter members of Tuscan Lodge in 1858 were distinquished members of the local community that had affiliated from their Mother Lodges. They were:

The first Worshipful Master of the Lodge Alfred Boultbee was a lawyer, Reeve of the Village of Newmarket and the Village's solicitor. The Lodge Secretary was William Trent, a bookkeeper and the partner of Robert Simpson whose merchandising empire started in Newmarket before it moved to Toronro. The first Treasurer was Nathaniel Gamble. The first candidate to be Initiated into the Lodge on March 19, 1858 was Joseph Cawthra, the son of John Cawthra, a wealthy merchant in Newmarket whose building still stands at the north-west corner of Main and Water Streets. John Cawthra married a daughter of John Bentley, who was the second Worshipful Master of Tuscan in 1859. Initiation fees in 1858 were $ 25.00 and annual dues were $ 3.00. Tuscan's earliest membersship was composed mainly of merchants, millers, doctors and lawyers. Today, the membership is drawn from a wide spectrum of the community. Initiation fees are $ 400.00 and annual dues are $ 100.00. Many of Newmarket's mayors, reeves, councilors and other civic officials have been members of the Masonic fraternuty.

When Tuscan Lodge was chartered in March 1858 it was a member of the Ancient Grand Lodge of Canada, which in its previous incarnation as the Provincial Grand Lodge of Canada West had declared its independance from the United Grand Lodge of England on September 9, 1857. Tuscan Lodge was originally numbered 66 on its register, and the Grand Master of the Ancient Grand Lodge of Canada was Sir Allan Napier MacNab, the former Speaker of the Legislative Assembly of Upper Canada. Meanwhile, there was in existence another Grand Lodge in Canada West called the Grand Lodge of Canada, which was an assembly of Lodges that had declared their independence from the Provincial Grand Lodge of Canada West on November 2, 1855. Its Grand Master was William Mercer Wilson. On July 14th, 1858 articles of union were approved by the members of both Grand Lodges. The Ancient Grand Lodge of Canada was formally declared dissolved and its lodges immediately affiliated with the Grand Lodge of Canada. On the following day delegates met in St. Andrew's Lodge Room, Toronto, and elected Most Worshipful Brother William Mercer Wilson as Grand Master and Right Worshipful Brother Thomas Ridout as Deputy Grand Master of the United Grand Lodge of Canada. Official acknowledgement and recognition of the newly-formed Grand Lodge of Ancient Free and Accepted Masons in Canada was eventually given in December 1858 by the United Grand Lodge of England. Tuscan Lodge in Newmarket was renumbered as No. 99.

With the expansion, and later contraction, of Masonic membership in Ontario over the years, the districts that Tuscan Lodge has been part of have changed seven times in the last 150 years and now is a member of Toronto York District (2006).

In 1945, at the Annual Convocation of Grand Lodge, it was recognized that while special awards were presented for services rendered to the Craft by Past District Grand Masters , Past Master of the Lodges and other Grand Lodge Officers, no awards were available for the valuable services given by brethren who never aspired to those offices. In many cases, their valued continuous Lodge activities did not lead to the Chair of King Solomon. Hence, the William Mercer Wilson Medal for distinguished service to the Craft who had not served as the Worshipful Master of a Lodge was inaugurated. One member of Tuscan Lodge was awarded this Medal, namely Brother George Wakelyn Luesby, who was initiated into Tuscan Lodge on June 26th, 1952 and served as long-time Historian of the Lodge. He received the medal at a reception held on May 1, 1992. R. W. Bro. C. Edwin Drew, the Deputy Grand Master of Canada in the Province of Ontario and R. W. Bro. Robert E. Denison, D.D.G.M. of Torono District 5 presented Bro. Luesby with the William Mercer Wilson Medal for Neritorious Service to Freemasonry and to the community at large. Bro. Luesby P.T.T.G.L.A. on January 5th, 2003.

On March 19th. 2008, Tuscan Lodge celebrated its 150th Anniversary at Madsen's Greenhouse and Garden Centre with M. W. Bro. Allan J. Petrisor, the Grand Master of the Grand Lodge of Canada A. F. & A. M. in the Province of Ontario in attendance accompanied by many current and Past Grand Lodge Officers among which was R. W. Bro. Rea Gibson, D.D.G.M. of Toronto York District. A good time was had by all.
