LOCAL CURRENCY IS CDN US BANK ACCOUNT G/L NOT BALANCING
you need to first find out what is causing the imbalance. There are a few things to investigate
It could be incorrect currency conversion rate. Go to currency page for cdn if your local currency is usd. Or the other way. check the exchange rates.
It could be postings made directly to the gl account without going through the bank subledger. To find out you need to go to g/l ledger entries and filter for the g/l account to find out what is causing the imbalance.
I won't recommend you to adjust gl account without finding out what the issue is.
if you are certain you just want to adjust the gl account, you could go to general journal and choose a balancing account which is not the bank account.
