I don't think you can get those high rate here from Canadian Banks. I guess IngDirect has a high rate for us saving. For GIC, I guess you have to call a bank by bank or go to the website for rate quotation.
BTW, US Bank should have a little higher rate than Canadian. But I didn't find one here until now. You may can open a US account in US. Then put your money there and you never pay US tax
