Relations between Boston, Massachusetts, United States and Halifax, Nova Scotia, Canada date back to the founding of Halifax in 1749, when Boston businesses had an interest in the new settlement for shipping and fish trade. The bond between the two cities became strongest following the Halifax Explosion in 1917, after Boston sent significant aid and disaster relief to Halifax.
Halifax Explosion
On December 6, 1917 at 9:04.35 AM, the Halifax Explosion severely destroyed much of the city. Boston authorities learned of the disaster via telegraph, and quickly organized and dispatched a relief train around 10:00 PM that night, to assist survivors. A blizzard following the explosion delayed the train, which finally arrived in the early morning on December 8, and immediately began distributing food, water, and medical supplies. Many personnel on the train were able to relieve the Nova Scotia medical staff, most of whom had worked without rest since the explosion occurred.
Christmas Tree tradition
In 1918, Halifax sent a Christmas tree to the City of Boston in thanks and remembrance for the help that the Boston Red Cross and the Massachusetts Public Safety Committee had provided immediately after the disaster. That gift was revived in 1971 by the Lunenburg County Christmas Tree Producers Association, who began an annual donation of a large tree to promote Christmas tree exports as well as to acknowledge Boston's support after the explosion. The gift was later taken over by the Nova Scotia Government to continue the goodwill gesture as well as to promote trade and tourism. The tree is Boston's official Christmas tree and is lit on Boston Common throughout the holiday season. Knowing its symbolic importance to both cities, the Nova Scotia Department of Natural Resources has specific guidelines for selecting the tree. It must be an attractive balsam fir, white spruce or red spruce, tall, healthy with good colour, medium to heavy density, uniform and symmetrical and easy to access. For the Christmas tree extension specialist in charge of locating it, the "tree can be elusive, the demands excessive, and the job requires remembering the locations of the best specimens in the province and persuading the people who own them to give them up for a pittance." Most donors are "honoured to give up their trees... most will gladly watch their towering trees fall" since everyone knows the reason it is being sent to Boston. The trees don't often come from tree farms, but instead from open land where they can grow tall and full. It is so important to the people of Nova Scotia that "people have cried over it, argued about it, even penned song lyrics in its honor."
Many of Halifax's people are also able to receive the Boston TV stations, including: WGBH-TV, WBZ-TV, WCVB-TV, WBTS-CD, WSBK-TV and WFXT, on TV providers like Eastlink and Bell Aliant Fibe. WLVI was the only station that's not available on most cable systems in the Halifax area. They are also able to receive a fair amount of Boston AM and FM radio stations in the Halifax area as well.
