Why invest in Canada at all is the real question, Larry. Dollar will be going down, very sub-par GDP growth, a tax-loving Lib government bent on scaring successful people out of Canada, and rising carbon taxes to boot (where the US will have none). And Trump and co. could still really screw us. 

There is really no incentive, other than the dividend tax credit for taxable accounts. That's why I will buy US, or international stocks and ETFs (even Canadian stocks that do most of their business internationally like BAM.A). Better covered call choices for non-taxable accounts would be ZWH or ZWE - great income and diversity and NOT Canadian stocks.
