Final answer:
Voluntary intoxication is not recognized by Canadian courts as a reason for a noninsane automatism state because it is a result of a deliberate choice to consume intoxicants, as opposed to uncontrollable conditions like sleepwalking, carbon monoxide poisoning, low blood sugar, or a stroke.
Step-by-step explanation:
The circumstance that would not be recognized by Canadian courts as a reason for a noninsane automatism state among sleepwalking, low blood sugar, voluntary intoxication, carbon monoxide poisoning, and stroke, is voluntary intoxication. This is due to the legal principle that individuals are responsible for their actions when they have voluntarily consumed an intoxicating substance. Unlike other conditions listed, which may occur without a choice or intention from the individual, voluntary intoxication is a deliberate action, and courts generally hold individuals responsible for crimes committed under its influence.
