**Table A3** Should we replace nuclear plants with natural gas-fired ones? This table compares actual Ontario grid CO₂ emissions from the last hour with those from a grid in which gas has replaced nuclear.
Actual Ontario grid	Gas replaces nuclear
72	5,238
5.53	402.38
Tons CO₂ CIPK, grams If gas had replaced nuclear last hour, Ontario power plants would have dumped enough CO₂ to fill Rogers Centre 1.8 times. As it was, 72 tons were dumped, which would fill Rogers Centre 0.0 times.
