Do you mean Baltimore, Maryland or the Baltimore an hour east of Toronto. Baltimore, Ontario has a neat little shop run by Steafan Hannigan and Saskia Tomkins that hosts house concerts, sessions, jams, lessons and many more folky events. The nearby towns of Port Hope, Cobourg and Grafton have many folk gatherings including a shape note group. The Shelter Valley Folk Festival is held near Grafton, a 20 minute drive from Baltimore.
