You could go with Koodo prepaid, get a $15 plan and a $30 300 long distance add-on. That would translate to $0.15/min. You would need a cell phone though.
That is a shame as I was paying 30 dollars a month for unlimited calling anywhere. More convenient than having to rush out and get a calling card. I live in the country so calling cards are not a quick run out to the store. I wish I had been told that prior to changing my landline.
