Is the Niagara Peninsula really a peninsula?

Yes, it is. The Niagara Peninsula is indeed a peninsula. Located in the Southern Ontario region of Canada, it is a distinct stretch of land that juts out into Lake Ontario. The peninsula is bounded by Lake Ontario on the north and west, the Niagara River on the east, and Lake Erie on the south. With its unique geography and location at the confluence of two major lakes, the Niagara Peninsula is considered a prominent geological feature and a significant peninsula within the province of Ontario.
