I got it registered! I was careful to read the rulebook as I went, so thankfully that paid off and it was found to be compliant. Alberta requires a windshield wiper, sprayer and defogger. The sprayer was easy enough, and I took a page out of Jack's book for the wiper. It clips onto the upper frame and is fully automatic, as is required. For the defroster, I bought a very cheap 12v heater. It and the wiper can be removed and placed in a bag until needed.
I had to sew my own boot cover, and although I have never been accused of knowing my way around a sewing machine, I am happy with how it turned out.
I also needed to rebuild the rear end when some metal shavings got in there. My own dumb fault, and a long story. I took the opportunity to press in new bearing races (something I'd not done the first time around) and installed a clutch type LSD.
After getting the car registered, I promptly went to an autocross event the next day. It was a ton of fun, but I was way over the noise limit and was not able to run in the second half of the day. 95.9 decibels and the exhaust was on the opposite side of the car from the meter! I have ordered a Car Chemistry muffler insert, fingers crossed it helps. The drone is almost ear-splitting at highway speeds, too.. But, beyond that, the car did great. I did resist the urge to push it hard, and I can tell I need to reduce my tire pressure from the 30psi I started at, but it feels like it's going to be fast.
I also went to a weigh scale today. 290kg (638lb) front, 370kg (814lb) rear, 660kg (1450lb) combined. That was with a quarter tank of fuel, myself, and some tools on board. After subtracting my and my tools weight (I won't say how much was me vs the tools), the car comes out to 1250 lbs! Very pleased with that number. For the purposes of useless bragging rights, that puts me just under a Hellcat in terms of lbs/hp with no driver, haha.
Here's a video of the third and final run at autox. Forgive the terrible start, it's a brand new clutch and I am very much not used to it.
