OK, colour me surprised and pleased. Bell has published a complete schedule of the events covered by their five Olympic channels (SD 381-385, HD 995-999) on their website. On some -- but not all -- days, they cover every event. On busy days, it looks like they alternate between doing Hockey & Curling on one day, and everything else on the next day, but I haven't studied their schedule in enough detail to confirm that.
The timezone selection feature of their pages doesn't seem to work; everything is listed in Eastern Standard Time, regardless of the selected timezone.
There continues to be ambiguity about whether a single order will cover one day or all days. The descriptive text at the top of each day's listing says: which suggests that one order should cover all days. On the other hand, each page says when it can first be ordered, only two days prior. For example, the page for the last day, Feb 28, says: which suggests that each day must be ordered separately (up to 48 hours in advance).
