Inet-cash have been reliable for me for the last 3 years. Payout on time via wire transfer.
They are based in Germany which has the most adult sites after the US. The majority of the site is in German but is not too difficult to translate using babelfish or just email them and ask them if they accept candian webmasters they have always answered my emails sent in English (does take them a bit longer than emailling in German though)
