Actually you've missed your opportunity to get involved with Regionals, if your listed location is correct, because Ontario Canada is switching to the District System for the 2017 season. Actually that is good since that means there will be a large need for new volunteers with the increase in the number of events and the fact that there will likely be weekends with 2 events.

So as the others have said you need to let the local leadership know that you want to be involved. I'm not sure if there will be any off season events in your area this year but if there are it is possible that the District administration will take that opportunity to hold try outs and training for various key volunteer positions.
