MR currency translation

I have CDN parent company USD sub company.  I am setting up a trial balance (initially Income Statement and Balance Sheet to following).

I have USD balance sheet account in the sub with credit balance $100 at the end of last year.  The balance at the end of August is $0.

Being a balance sheet account I have to pick YTD in the column set up to get the ending balance.  I want to do currency translation and the CAD is picking up the net change for the period of Jan to August.  which is Debit $100.

Do I have to enter an opening currency translation for all my balance sheet accounts so that the currency translation will go to zero?

thanks!
