I worked closely with Dean Acreman when I was on Faculty Council this past year, and with Dean Morse when I was on Faculty Council the year before.
As others have mentioned. the role of Dean is 99% administrative and doesn't actually seem to require any knowledge of law.
I met the candidate for the real Dean position before I graduated. The hiring process was long and when they visited it was the last step before they were supposed to decide to accept the position. I graduated before hearing if that candidate had officially accepted. If they have accepted, I would not be surprised if the pandemic has made it difficult to move their family to Kamloops. Or perhaps the pandemic has made that candidate rescind their acceptance.
Installing an Interim Dean doesn't give Clocktower much, if any, power over the law faculty. Major decisions are made by vote at Faculty Council which is comprised of the key administrators, all tenured profs, and the main executives from the Society of Law Students. An Interim Dean wouldn't be able to unilaterally make important decisions for the entire faculty.
It's always the immature/elitist law students who make the culinary school the butt of a joke.
Going to Ivey may limit your ability to get a 4.0, but assuming you can stomach the tuition, I'd say go.
OP something to be aware of - yes there is an 80% curve but the standard deviation is very tight. Top 25% at Ivey is 82% in HBA1 and 84% in HBA2. So assuming you are top 25% of the class both years (which is saying something) a 3.9 is unlikely never mind a 4.0. That said, it is realistic to walk out with a 3.7. That weighted with your BMOS courses would be competitive everywhere on a GPA basis.
Ivey's real benefit isn't helping you get into law school, but setting you up to succeed once you are already there (at least in my experience). I found HBA1 to be stressful and a lot more work than I was accustomed to - many people have similar sentiments about their 1L experience. But, since I was already put through the pressure cooker once, 1L just wasn't as jarring. You are accoustomed to being around other smart motivated people, you have been trained and incentivized to participate in class, and Ivey's case method is similar to the socratic method used in law. All of this may help you find your footing early. The second and most tangible benefit is the work experience opportunities. It helps set you apart in the application process when you have brand name work experience. Especially compared to most students coming straight from undergrad.
Money aside, it's a no brainer to go. Is it worth the extra ~$50 grand, that's for you to decide.
