This post is troubling indeed. Before I get into that, please clarify that the visa he ultimately obtained was as your spouse, is that right? If not, what was the nature of the visa. Also, unless you prefer not to say, can you tell us whether you too are residing in British Columbia, or did he decamp on his own to BC?
Back to the worrying aspects. You have alluded to threats against your parents. I suspect that I am not drawing too long a bow in using the word "threats". I have seen such cases in the past. I doubt the "warnings" you have been given are benign, but if they can be cast in that light, things might not be so concerning. Only you know exactly what has been said, when, in what context, etc. But my senses tell me there is a strong element of abuse here and that this is someone who should not be encouraged to stay in Canada.
If what my nose is telling me is any guide, you may already have been the victim of not just marriage/immigration fraud, but quite a serious criminal offence under the Criminal Code of Canada,
viz:
Uttering threats
- 264.1(1) Every one commits an offence who, in any manner, knowingly utters, conveys or causes any person to receive a threat
- (a) to cause death or bodily harm to any person;
- (b) to burn, destroy or damage real or personal property; or
- (c) to kill, poison or injure an animal or bird that is the property of any person.
The application of the above provision in our courts is a matter of which I have some knowledge and what you describe (albeit in scant detail) might fall readily within its scope. It probably does.
I would urge you to get some advice from a trusted/trustworthy source. You have said you want to teach this man a lesson, so it sounds like you are willing to take some action. While wanting to teach a lesson is an entirely understandable emotion, that aspect should perhaps not dominate, but from what you have related, you have been grievously victimized and it should not be allowed to pass.
