Since I live in New Mexico, we discuss volcanoes often. There are many active ones right in our backyard.
Yes, there could be volcanoes in Newfoundland--both active and inactive. Look at its neighbor Iceland and all its volcanoes!

No, Newfoundland is on a passive margin and the nearest active margin is thousands of kilometers away. I heard of some research involving the switching of passive margins into active margins in a seminar, but it is a stretch (of millions of years) to go from detecting signs of a possible switch to the development of a volcano.

In the very ancient past, there were several types of settings that produced the old volcanic rocks that crop out at the surface of parts of Newfoundland--these settings include island arcs (with island arc volcanoes) and mid ocean ridges (which produced ocean floor-type volcanic rocks and plutonic rocks-"ophiolites". Here are two very nice web pages talking about and illustrating the long geologic history of Newfoundland:

What's your question? There are signs of extinct volcanoes, eg Avalon Peninsula. You can identify the cone.
