Prince, Esq.^[6] The building was completed in 1881,^[1] totaling CA$80,000 (equivalent to $2,903,680 in 2023).^[6]

Historically, the building was used to host Masonic Grand Lodge of New Brunswick meetings annually, including once in 1934 which included John Babington Macaulay Baxter, a former Premier of New Brunswick who served as the province's Grand Master at the time.^[7][8]
