I think the idea that walking through a cemetery is scary or should be, is created by the media. In reality, its usually quiet, tends to be damp, among the trees, or windy if there are few trees. I've photographed an old cemetery which was on the edge of a farm field, only one tree. It was very cold and windy. That was perfect atmosphere for a movie. But, they would have needed a story to make it creepy. The reality was just bitterly cold, not scary at all.I found this post, which included a quote from Loren Rhoads, about travel and exploring cemeteries.
“I look at them as open-air sculpture gardens,” Rhoads said. “There are some places in the world where it’s museum quality, and it’s just there for anyone to visit and take a look.”

Loren has written, "Wish you Were Here" and "199 Cemeteries to See Before you Die". The first is about US cemeteries and the second about cemeteries around the world. Also, her site Cemetery Travel.
You can also find her Cemetery Travels Notebook, for your own exploring and notes, from her Etsy shop, CemeteryLibrarian.
I will see if I can find more about and from cemetery explorers and photographers in Canada, and Ontario especially.
