This is definitely one of the most helpful, informative posts I've seen on this forum in a while. As a uni grad and current law school hopeful, I would agree and second nearly everything @goalie mentioned!
Also, don't worry about the mean and immature initial posts you received - they're just trolling and trying to discourage you from the comforts of their keyboards. Although I do agree some of the previous posters, don't always expect the people on this forum to "spoon feed" you and to "hold your hand" throughout this process. Don't expect the people here to applaud, congratulate you and give you external validation for your newfound decision to pursue law. Many people on here, including myself, have put in the "hard work" and feel we have "paid our dues", spent tens of thousands of dollars to pay for undergrad (and sometimes further schooling), and spent hundreds of dollars for applications, LSAT materials, etc. I'm here because I'm also procrastinating finishing a project, so why not pour my thoughts for free on good ol' LS!
That being said, I do empathize with your situation and want to offer some advice to you, @IdontargueIdebate. I sincerely wish someone had told these things to me before I started this whole journey:
1. Choose an undergraduate program/ courses you are genuinely interested in. If law school doesn't work out, choose a program that will allow you to have a decent, stable job right after graduation. Perhaps somethings like business, commerce, or communications. Even nursing.
2. Don't go into political science, economics, history, English literature, and the like just because it tends to attract the pre-law types. I did a science undergrad and the majority of my peers gunned for medicine or physical therapy. It can be a pretty bubble-like environment where everyone has tunnel vision and is super competitive with each other (depending on the university), but that's not always the case. In fact, the courses I enjoyed the most were actually outside of my program (music history, classics, languages). So choose what you're interested in if they allow it!
3. Unless you went to something like an Ivy League school or Oxford, Canadian law schools don't really care where and what program you got your undergrad from. So my advice: choose a less competitive university with a more collegial, supportive environment. Generally, smaller schools with smaller class sizes like TRU, Guelph, and Mount Allison are arguably less competitive and snarky than schools like U of T.
4. There are some Canadian law schools that let you in after 2 or 3 years of undergrad study. Sask Law only requires 2 full years of undergrad study. https://law.usask.ca/students/becoming-a-law-student/applying-to-law.php
5. Getting in after 2 or 3 years is certainly very uncommon, but not impossible!! I wouldn't compare them to "unicorns" though. I know a handful of people who got into law schools in Ontario after their 3rd year. Mind you, many of them gunned it since day one of university, spent their summers gaining relevant volunteer/ work experiences, practically had no social lives, and had amazing GPAs. Some also had lawyers as parents, so maybe that helped in some way too. Gotta keep yourself motivated!
6. Don't go to the UK or Australia for law if you want to practice in Canada. Lots of info and reasons why can be found on this forum.
7. You say you want to go into "family law" after the experiences from your divorce (among other reasons). But why not go into social work, family counselling, or paralegal studies? Have you considered working in a setting like an NGO, charity, community centre, etc. without being a lawyer? You have to really ask yourself these questions: Is law really something I want to do? Am I willing to commit at least 5 - 7 years to get a law degree? Will another profession or program satisfy my interests? I think these are really important questions before investing over half a decade, thousands of dollars on tuition, applications, and LSAT fees (and lost income), and effort for something that may not be guaranteed.
8. Do your research. I'd start with applying to undergrad programs. For example, in Ontario, the deadline to apply for undergrad programs (through OUAC) is January 17, 2018. There's a website out there to check what high school courses are required for various programs and what the typical high school average is for acceptance.
Overall, I'm not trying to discourage you, I'm trying to be realistic and practical. You can take my advice with a grain of salt, but I mention these things because I think before committing yourself to the long journey to law school and the legal profession, you should make an informed, logical decision that covers all bases. It will honestly save you a lot time, money, effort, headaches, and stress! Honestly, there are certainly some things I wished I did during my undergrad to make it a heck of a lot easier and less stressful (some of them I mentioned above). But, like many others have said on this discussion, there is no quick or easy to get into a Canadian law school. None. Well, unless you're Quami Frederick, but that ended in calamity for her at Osgoode about a decade ago. There are no shortcuts.
Anyways, I hope you find this information helpful...I'm also procrastinating a project and should really get back to it now! But, remember, you can do anything you set your mind to and don't let the naysayers and internet trolls convince you otherwise! If you really want something and are willing sacrifice for it, don't let anybody rob you of your dreams. Believe in yourself! Pay your dues like everyone else who was has studied for the LSAT, attained an undergrad at least, gotten into law school, and survived it. Where there's a will, there's a way my friend!
Wishing you the best of luck with whatever decision you make.
