For the disposition date if yo have many stocks do you just use Dec 31?

Yes, that should be fine. The CRA doesn't really use the date for anything, it is for info purposes 

Hi @tom178,

The date of disposition would be when the particular stock transaction (sale, transfer, etc.) was completed. You would need to enter the actual date of the transaction for each stock.

Thanks.  On Saturday I lust used Dec. 31 and when I had it checked iver the Turbotax lady said it was good
