A more likely scenario in which the TA provides generalized information.
TA: You will need a valid passport that does not expire (before) or (however many months required after) your return. Canadians require/don't require visas for ...
I would expect a good TA to also provide advice to non-citizen residents. Such as to check that their residency status allows exit and return and the possible need for multiple entry visas when sailing round trip out of countries that require a visa.
The TA has to have established traveller citizenship & residency status in order to ethically sell international travel. It is the job of a good TA to inform customers of usual documentation requirements.

I was going to post the links, but they are not working at the moment. If I recall correctly, you need to enable voice over LTE. The Key 2 allows one of several network type settings.
Sheesh . . . is is possible for the government to do a single thing without someone getting confused and complaining?
What is confusing about the guidelines?
If I tap on a picture in a post it goes to a full window display. Took me the longest time to notice the black x in the top right corner. This is because the picture background is also black. Is this because of local settings on my tablet / browser or is this site specific?

Rules for cruise ship passengers that test positive for COVID are detailed at https://travel.gc.ca/travel-covid/travel-restrictions/cruise#symptoms.
Since you tested positive on the cruise the isolation period is 10 days. As noted in the link, had you not tested positive on the cruise but after disembarking, the isolation period would be set by local public health authorities.
