Looking for free intra day data history

Hi everyone,

I am looking for a web site where I could download free intraday data history for American and Canadian Stock exchanges. Yahoo Finance has something similar for daily, weekly, monthly: that's exactly the format I am looking for.

I am not interested in a software to do the download (even when free), I want the raw data in a text file (or similar) so I can rework it to my taste.

Thank you for your help.
