- I'm a little old school, but tend to buy series that I can't get (or cheaply get) through Canadian services on DVD or BluRay when they come out. Just another option if you can wait a few months. Wait a few months after they are released (over a year after air date) and you can get second-hand DVDs very cheaply online.
Another option if the series is shown in Canada is to wait until the series is over (or almost over) and binge-watch the episodes on demand for a month. Super Channel has most series on demand and is available for $10/month from many providers.
