Could I use one thermostat to run two heating pads?

As long as they use the same amount of voltage you can run them from one thermostat. Otherwise one will be overpowered / underpowered, depending on which pad the sensor is placed on.

If your not sure what voltage the heat pads use to get to temp, then just stick to same size, same brand heat pads and you should be fine.

Its the "watts" that you need to look at they are all going to be 120v most likely. Every 120 watts at 120 volts = 1 amp so 240 watts at 120v would be 2 amps. You can run two off the same thermostat if they are the same size and watts and the cage is set up the same but they will fluctuate some still. you need to put the probe from the thermostat directly on one of the heat pads and check it often because if the heat pad the probe is on fails the other will get very hot. Or you could buy a herpstat II it can control two cages with one unit.
I just noticed your in Canada. I'm not sure what voltages they use up there but they still need to be the same voltage and wattage.
