It's been 99 years since the Halifax Explosion - at the time, the largest human-made explosion in history. The north end of Halifax was wiped out, and the blast shattered windows in Truro, 100 kilometres away. Nearly 2,000 people lost their lives, including dispatcher Vince Coleman. | Historica Canada
