Here’s What You Need to Know About the Halifax Explosion of 1917

Curious about the Halifax Explosion but not sure where to start? We’ve got your back.

We’ve pulled together a basic summary of the disaster that shaped Atlantic Canada’s largest city with a catastrophic collision on the morning of December 6th, 1917; the infamous Halifax Explosion.

Cities around the world have been shaped by the major disasters in their past. Events like the San Francisco earthquake of 1906 and the Great Chicago Fire of 1871 are responsible for moulding both the cultural and physical aspects of their environment. Unfortunately, Halifax is not exempt from catastrophic disaster, having experienced the Halifax Explosion of 1917.

On the morning of December 6th, the Norwegian aid ship Imo collided with the French arms vessel Mont-Blanc in the narrows, the waterway linking the Bedford Basin and the Halifax Harbour. Although the collision itself was minor, it ignited a fire that burned for twenty minutes, drawing spectators to the shoreline who were unaware of the grave danger presented by the fire. Only a few naval officers and Vincent Coleman, railway dispatcher, knew the explosive cargo that was aboard the Mont-Blanc.

At 9:04 AM, the Mont-Blanc exploded. It destroyed 1,630 homes, and left 12,000 others damaged. Over 6,000 people were left without shelter. Unsurprisingly, “hardly a pane of glass in Halifax and Dartmouth was left intact.” To make matters worse, the city was hit by a devastating blizzard the following day, covering the area in over 40 centimeters of heavy, wet snow.

The death toll of the Halifax explosion “rose to just over 1,900. About 250 bodies were never identified; many victims were never found. Twenty-five limbs had to be amputated; more than 250 eyes had to be removed; 37 people were left completely blind.” (Maritime Museum of the Atlantic). Aid workers came from as far away as Boston, which is why Nova Scotia now sends them their annual Christmas Tree for the Boston Common each year.

Did You Know?

  • The Halifax Explosion helped spur the creation of the Canadian National Institute for the Blind (CNIB). Over 1,000 people incurred serious eye injuries from airborne shrapnel, “which left them blind or with significant vision loss.
    A staggering 250 eye removals were performed over a period of two weeks following the explosion, an additional 206 survivors had lost one eye and required monitoring to ensure they retained their vision in the other, and 260 more people had glass embedded in their eyes
    ” (CNIB). CNIB volunteers worked with survivors to successfully navigate their new reality, helping them learn new skills, including reading braille, and relearn skills that were suddenly difficult without vision.
  • The Halifax Explosion was the largest man-made explosion prior to the Atomic Bomb.
  • There is a Halifax Explosion Book of Remembrance on display at the Maritime Museum of the Atlantic. The book contains the names, ages, residential address at the time of explosion and burial location of all 1,951 people lost in the explosion. There is a reference copy of the book available at the museum for public consultation. You can also access the book online here.
  • The Chebucto Road School (now the Maritime Conservatory of the Performing Arts) served as the main mortuary for victims of the Halifax Explosion. The morgue operated in the basement of the building, while the classrooms were used as offices for the coroners. The system used to number and describe the bodies was modelled after the identification process used to identify Titanic victims.
  • While there has never been a complete tally done on the financial cost of the Halifax Explosion, $35 Million USD, in 1917 rates, is commonly used as the total. The estimate includes “losses to government, shipping and railways, houses, churches, manufacturing plants and inventories and personal belongings” (CBC).
