Look, there is only one wrong question to ask about academic misconduct - and it's been asked here many times in the past. Do you really need to disclosure it? The answer is yes. Any time you are asked a direct question about this, you need to answer truthfully. Note that you'll also be asked when you apply to be licensed as a lawyer, assuming you get that far. Now kudos for the fact that you haven't asked that question, because when people do ask it often reveals a mindset that's not entirely in line with legal culture. But beyond answering this question which you haven't asked, no one here can comment definitively at all.
I'm mainly answering to provide this context. I'm a criminal defence lawyer. And I'm frequently asked some variation of this question by clients - "will my past mistake stop me from doing X?" Again, it isn't often I have a definitive answer. But I've observed that many people who aren't defence lawyers like to get self-righteous when addressing this topic. It's human nature (though not the best part of human nature) to enjoy seeing other people suffer from mistakes that we ourselves have avoided. The Greeks understood this. And so in answer to an unanswerable question - how much will schools, the law society, etc. choose to care about this - it's likely you are going to get a lot of extreme replies that suggest you've permanently fucked your life. That doesn't make it true.
I will observe that law schools have admitted students in the past who have been convicted of serious crimes, and so have law societies. Your individual situation is unique and I won't presume to suggest what will happen. But be honest in reply to any direct question - that's your obligation. How you choose to frame your experiences, or if you choose to highlight them at all beyond this, is entirely your choice. Don't lie about the past, because when you do that it creates new offences of dishonesty. But you also have no obligation to inhabit the identity full-time, as though you are permanently defined by your past. You're entitled to move on. And don't let anyone else imply otherwise.
No one would be able to answer whether you have any chances at Canadian law schools or not.
If you really reflect on your issues of academic misconduct and you are indeed serous about going to law schools, I would like to say that your personal statements may need to talk about your academic misconduct in the past and discuss how you personally or academically have grown by dealing with these wrongdoings.
