**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
808	6,043
44.45	332.41
Tons CO₂ CIPK, grams If gas had replaced nuclear last hour, Ontario power plants would have dumped enough CO₂ to fill Rogers Centre 2.1 times. As it was, 808 tons were dumped, which would fill Rogers Centre 0.3 times.
