Ad Sensing

i want to put text ads on my site and make profit.
im looking for an alternative to googleadsense.
i cant use yahoo ads because i am in canada and that service is in the usa. i dont want to use adbrite because they are for my social security number which i dont want to give out. i looked into bidvertiser but i dont think i can get much profit from that because i have to get bids. can some one help me?

Nothing comes quite close to Adsense in terms of revenues, payouts, volume of advertising, and reliability.

Check out Intellixt http://vibrantmedia.com/site/web_01a5.htm (you can see an example of how it looks like at Entrepreneur.com). They are very picky with the types of publishers they work with but they have one of the better payouts out there

But still, nothing comes quite close to Adsense.
