Cart misbehaving, posting wrong prices after installing Canada Post module

I'm trying to get the cart in CAD. I'm in Canada, it makes sense :)

Well, I enter a product, price is $11.95 but in the store it's posting $12.02.

I have no idea why. I have it set as CAD default in currency localization.

Where else could things go wrong. I had installed IPN. BUt it was workign fine. Then I did install the certapay, it was workign fine.

I installed the Canada Post module, and it all went down the tubes.

Not sure what would affect that, it's a shipping module.

Ideas? Please. I'm hoping to get it all sorted out for August 1.

Ok, I figured out what it's doing, but not how to fix it. It is taking the posted price as USD and converting it to CAD. What files need editing to fix this? The difference shown is the conversion rate. I tried deleting the USD from the currencies, but then it gave a value of $0

In your english.php file, do you have your default-language-currency set to CAD as well ?

Yes it does have CAD.

Is there anywhere else I must change? Thank you very much for your assistance.

In your admin list of currencies, what is your exchange rate for CAD, and for USD ?

If your store is supposed to be defaulting to CAD, then you should be setting CAD to 1.0000 and your USD should then be the appropriate exchange rate from CAD to USD.

Yes it is set that CAD is the default and it's value is 1.00

Ok, the issue resolved, but I didn't do anything ?? It just started functioning properly again.
