Nova Scotia's Christmas tree gift to Boston has been officially lit up on the city's common.
The 15-metre white spruce is an annual token of gratitude to the Massachusetts city for its help after the Halifax Explosion in 1917.
Friday, Dec. 6 marks 96 years since the explosion, which killed about 2,000 people and injured hundreds more.
A delegation of Nova Scotians travelled to Boston for last night's tree-lighting ceremony.
