In case anyone is still wondering, all this means is that the spouse's taxable income (line 26000) is equal to or less than their federal non-refundable tax credits (excluding a few, such as donations and medical expenses), which means that they will have no federal tax to pay. So, if you look at the generated Schedule 2 and see that this is the case (line 36100 is $0.00), then you just answer "Yes" to the question and you are good to go. To be completely clear, this is not asserting that they have no income. It is asserting that they have no federal tax to pay.
