This year the Canadian Folk Music Awards are being held in Ottawa. Details and schedule are available here: https://folkawards.ca/events/ottawa-2017/
For the Celtic-inclined, there are two music jams on the weekend:
12-3pm Celtic Jam Session Deacon Brodie’s Pub (247 Elgin St.)
1-4pm Celtic Jam Session Patty’s Pub (1186 Bank St.)
Go have a listen. Expect experienced musicians, I'd venture to guess.
