There is mention of DRIP in current terms & conditions.
21. Dividend Reinvestment
21.1. We allow for dividends on stocks in your account to be reinvested and it can be done automatically if you instruct us to do so. Dividends on stocks will only be reinvested in the same stock where the dividend originated from. Instructions to reinvest dividends will not be carried out if your account has been suspended or restricted by us in accordance with this agreement.
So it seems to be matter of reaching out to T212 and instructing them to enable DRIP for eligible stocks.
