What was the name of Canada's October 13, 1989 stock-market crash?

Canada's October 13, 1989 stock-market crash was called the Friday the 13th mini-crash.

The event occurred when the Toronto Stock Exchange experienced a sharp one-day decline. A major factor was the collapse of a proposed leveraged buyout of United Airlines, whose financing difficulties unsettled investors and contributed to selling across markets.

The Toronto Composite Index fell 6.6% that day, making the episode one of the most severe single-day declines in the exchange's history. The crash was smaller and shorter-lived than the worldwide 1987 equity collapse, which is why it is commonly described as a “mini-crash.”

The name is sometimes confused with Black Friday or the 1987 Black Monday crash. Friday the 13th refers specifically to the Canadian market event on October 13, 1989, not to a general superstition-based label for every market decline on that date.
