I'm assuming that you have followed up on the various pointers in this thread. You really should refer to trac-cymru.org of which I was Director until I moved back to Ontario in 2011. The weekend course in the fall is a spectacular way of immersion if you can afford the trip.

Where in Canada are you? The National Festival of Wales is in Toronto over Labour Day; a bit light on trad but I'm doing 2 lectures on trad music so it's a start.

You should also Google Welsh Heritage Week and Cymdeithas Madog for info. CM has a CD of trad songs for Welsh learners and the course will be in St Catharines, Ontario next year.
