Struck out my "long-standing title" bit as CambridgeBayWeather was who capitalized it in January (as another Canadian, he would know to as per other major-event titles like Oka Crisis, October Crisis, Gustafsen Lake Standoff, Winnipeg General Strike et al - all major events with recognizable "proper names".  I don't see a previous move since its creation in '04 but I do see that the very first version used all-caps in the lede, indicating normal CANENGLISH usage and recognition of the importance of the event in Canadian history.
