Prevent automatic currency conversion

Description

I receive money in USD, I have a USD bank account. I live in Canada. Whenever I try to withdraw my USD funds, PayPal converts it to CAD, then the bank rejects the transaction. My primary currency is set to CAD. So now I’ve lost some money in an unnecessary conversion which will incur another loss converting it back to USD. It’s as easy as just not doing a conversion. Just send it as is; Or as it was too the bank…. And PayPal doesn’t seem to respond… To anything, how do I stop these conversions? I’ve looked at similar threads, I’m already doing what I’m supposed to as far as I know.
