Roberto is a retiree whose income is close to the level at which a portion of his OAS may be clawed back (repaid). He derives a high proportion of his taxable income from Canadian-dividend paying stocks. Why is this a disadvantage with respect to OAS? He will not receive the dividend tax credit if he losses part of his OAS. Investment income is not included in income used to calculate the maximum OAS threshold. The grossed-up value of the dividend is included in his income. Dividends are low return sources of investment income
