Folks,
I've been reading carefully the thread and I have a question for you: are you 100% sure the entry/exit forms are for all the countries you visited as a tourist?
I received the forms and annexes in french (my mother tongue) and it seems to me that the form is required for countries you were a resident of only (and they specified ''permanent or temporary). Now as you know Canada makes a status distinction between a tourist and a temporary resident, so I'm strongly thinking you only need that form for countries you are a citizen of or countries you lived in during the past 5 years, but not the ones you visited as a beach vacation (where, let's admit it, you drank and ate too much in 2016) do I make senses or not at all?
