Pier 4, like Bayfront Park, is one of Lake Ontario's youngest waterfront areas. The park itself was opened in 1993. It was a $9-million transformation of once industrial land into greenspace. The family-friendly beach sits beside one of Hamilton Harbour's popular recreational boating facilities. This giant bay was once an incredibly lush ecosystem but heavy use and fill by industry over the last century has left it one of the most environmentally challenged parts of Lake Ontario. As local government and residents work to restore the bay, places like Bayfront Park appear.

Oh, and you may want to know that there have been (very) occasional sightings of a cryptid - so keep your eyes peeled for Lake Ontario's own lake monster!
