What that title on the approach plate means is that you can either use it to do an ILS approach onto that runway or do an NDB approach or an NDB GNSS-overlay approach. If you have a GNSS/FMS certified for IFR you could use that to fly the NDB overlay approach, even if the NDB itself is out of service.
You will only see LNAV minima when it's an RNAV (GNSS) approach. In the case of that Montreal plate, if you were using GNSS/FMS (or ADF) to fly the approach, you'd use the NDB minima.
