The St Peter's Battery Provincial Park on the Atlantic Side of the St Peter's Canal offers you another easy dive site. Directly underneath the lighthouse are the 2 boilers and what seems to be a 10m long shaft from an old shipwreck. This place is usually full of lobster, but it is also worth to keep an eye on the smaller critters, like hermit crabs, snails, little sculpins, scallops, mussels, sea stars and urchins.
