Mayor Michelle Wu, the Boston Parks and Recreation Department, and The Province of Nova Scotia will host Boston’s signature holiday celebration, the 84th annual Boston Common Tree Lighting, on Thursday, December 3, from 6:00 p.m. to 8:00 p.m. in Boston Common, adjacent to the Visitor’s Information Center at 139 Tremont Street. Mayor Wu will be joined by Nova Scotia Premier Tim Houston, marking the 55th year that Nova Scotia has given a tree to the people of Boston as thanks for relief efforts following the December 6, 1917 explosion of a munitions ship in Halifax Harbor. Within 24 hours of the disaster, a train loaded with supplies and emergency personnel traveled from Boston to Nova Scotia to aid in recovery efforts.

At approximately 8:15 p.m., immediately following the celebration on the Boston Common, Mayor Wu will join the Friends of the Public Garden and the Committee to Light Commonwealth Avenue Mall to flip the switch to light up Commonwealth Avenue Mall in the Back Bay. The lights on the Commonwealth Avenue Mall will be lit from Arlington Street to Charlesgate.
