I mean, basic research shows that McGill always takes their sweet time. I've made this rant before - people apply to McGill knowing that professors are personally reviewing every single application and considering every aspect, from grades, references, LSAT, CV and personal essay. The law fac has to follow deadlines for CEGEPers, mature students and regular applicants. All of this is done while simultaneously teaching, grading and doing research. Most profs don't have TAs doing it. Plus there is a pandemic.
If you're wanting to go into law purely for the money - given where you are now - it doesn't make much sense. It's a big risk for a chance to eventually make 250k+, which would be the only way to make up the opportunity cost.
Personal injury can be very lucrative but starting out as a sole in PI is not easy by any means. Most, if not all files are on a contingency basis. When you start your practice as a sole you're going to have to find a way to fund your cases (disbursements, overhead etc.) before getting any settlement money.
Not saying it can't be done, it has been done by many successful small personal injury shops, but it is not easy.
I'll be frank, if OP is making six figures gross right now, the opportunity cost of going to law school is probably heavily on the "don't go" side. Trading 3 years of 6 figure earning power while young to go dump cash into an institution to get out and make.... six figures in the best case is lunacy. Take the money you'd spend on law school and sock it away in the market and be content you're likely going to come out ahead.
