I know, I know. But they're not accompanying you. If they were accompanying you, you would have listed them as accompanying in your PR application. Just because they're travelling at the same time and may stay at the same hotel doesn't mean they are accompanying you because you would have had to list them as accompanying in your PR application.
If your intention, though, is to get them into Canada and then find a way to have them stay, whether it be through extension after extension or H&C application, then you should have listed them as accompanying.
