Tax Loss Selling for CanadiansThe last trading date for 2018 for Canadian and US publicly traded stocks will be Thursday December 27th in order to record the gain or loss in the 2018 taxation year. Canadian stocks purchased or sold after December 27th are settled in 2019, so any capital gains or losses on sale apply to the 2019 tax year instead of to the 2018 tax year. The Canadian stock exchanges, such as the TSX, are closed on both Christmas Day and Boxing Day (Tuesday, Dec 25th and Wednesday, Dec 26th).
