Metabolic rate. The canary doesnt die fast because it is genetically sensitive. It dies fast because a birds metabolic rate is like a firecracker compared to ours.
Some birds have incredible metabolic rates --> take for example a humming bird.
However if I were to assume a canary has twice the human metabolic rate, it isn't a very good sensor. So, the canary dies half as soon? But the canary isn't even about poisonous gas. I believe it's about explosive methane gas, as their gas lanterns would need to be extinguished if the canary died, or else the gas leak that killed the canary could explode.
So, yeah, anyway. I think your information on this example is wrong, please feel free to correct me
