What Canadian company's stock crashes in a dramatic fashion in 2002?

In 2002, the Canadian company Nortel Networks experienced a dramatic stock crash. Once a leading telecommunications firm, Nortel's stock plummeted due to accounting scandals and the bursting of the dot-com bubble, which severely impacted the tech sector. The company's share price fell from a high of around $124 in 2000 to mere pennies by 2002, leading to significant losses for investors and ultimately contributing to Nortel's bankruptcy in 2009.
