Investigation:

We generally don't do much work in graveyards unless a particular one inspires us to do so. The Pembroke graveyard did yield some wonderful pictures,  one of which contained the face of a woman in an orb. Arguable yes, but a great picture and some very good sensations.
The Almonte graveyard was a very chatty sounding place for seekers of a spiritual nature.

Conclusion:

Activity yes, haunted not that we have found, or expect to.
