The check-in always takes place at the carrier that performs your ticket. Air Canada Jazz for your first journey. I' m assuming the first two trips are on the same date, so the last two are, and the Hawaiians are separated? Is Lihue your ultimate goal? Although I don't know anything about Air Canada Jazz, United tends to reject online check-ins for tied US travel unless you have provided all the necessary information (US address, passport data, etc.) in advance with your reservation.
Montreal should check you through to your ultimate goal on that date. On the same date, is the Lihue service a straight to? I' m not sure how they manage inter-airline Honolulu routes when you connect to an inter-island itinerary. I am also not sure whether Air Canada will issue the Hawaiian Airlines' Air-Board Card or whether you will need to receive it separately in HNL.
Generally, the carrier operating the first ticket will check you in on all itineraries. As I said, however, I am not sure about the connections between the islands.
