[40] Intention is not to be confused with motive. Motive is the reason why someone does something. It is possible to have a specific intention for doing an act that is different from the motive for that same act. If a person robs a bank to pay for medical treatment, the intention would be to commit the offence of robbery, while the payment of the medical expenses would be the motive. Motive is not an element that the Crown must prove, so it is important to differentiate between the required intention, which forms a part of the offence that the Crown must prove, and motive, which does not. R. v. Abdullah
A truly subjective test seeks to determine what was actually in the mind of the particular accused at the moment the offence is alleged to have been committed. In his very useful text, Professor Stuart puts it in this way in Canadian Criminal Law (2nd ed.), at pp. 123-24 and at p. 125:
What is vital is that this accused given his personality, situation and circumstances, actually intended, knew or foresaw the consequence and/or circumstance as the case may be. Whether he "could", "ought" or "should" have foreseen or whether a reasonable person would have foreseen is not the relevant criterion of liability.
...
In trying to ascertain what was going on in the accused's mind, as the subjective approach demands, the trier of fact may draw reasonable inferences from the accused's actions or words at the time of his act or in the witness box. The accused may or may not be believed. To conclude that, considering all the evidence, the Crown has proved beyond a reasonable doubt that the accused "must" have thought in the penalized way is no departure from the subjective substantive standard. Resort to an objective substantive standard would only occur if the reasoning became that the accused "must have realized it if he had thought about it".
