Why this rock is probably not a meteorite:

1) No fusion crust

2) It's got holes. Meteorites aren't full of holes like this.
What is it?

It's hard to tell from the photo. It resembles a piece of scoria, however it was found on the north shore of Lake Huron in a limestone environment. It might be silica (quartz) that had been deposited from solution in voids in the limestone.
