I'm on the same itinerary; ports are Juneau, Glacier Bay day with ISP in the evening, Sitka, Ketchikan, and Victoria. Three of mine were cancelled - Misty Fjords cruise in Ketchikan and both Craigdarroch Castle and then Butchart Gardens in Victoria (the former was several weeks in advance, as the castle wouldn't be open evenings at all this season).
We're fortunate that our highest priority excursions (dogsledding in Juneau and whale watching in Icy Strait) were still operating. I'd certainly be disappointed if all of mine had been cancelled.
