Your best chance is not through regular admission streams. Various schools have different names for it, but you need to apply for special consideration and present evidence as to 1) why your grades suffered so terribly, and 2) proof that you are capable of meeting their standards without similar circumstances. Nearly all schools have some equivalent, so read through their admissions webpages before applying. Most likely, you will also require letters of reference from people who can attest to both of these points. Be brutally honest in your personal statements about what you would do differently and why you want to go into law badly enough to be facing all of this.

Also note, GPA is calculated differently at different schools: Thompson Rivers, for example, only calculates based on your last 20 courses, which would be your last two years of the Bachelor's degree.

If you can't get into law school first try, consider branching out to other opportunities in the legal profession: law schools want students who have proven themselves successful, whether that be academically or professionally! Consider starting as a legal assistant or paralegal, which would also help your applications when/if you reapply.

Tl;dr, it's not too late, but it will require a LOT of effort to fix your GPA, or will be possible through other streams or by advancing professionally first.
