My MIL gave me boxes upon boxes of her old canning jars. The ones that she gave me are slightly taller and skinnier than the rest of my (thrifted) half pints. Why are some of them taller and skinnier vs wider and shorter? Could it possibly be US vs Canadian jars??

There are lots of reasons they may have updated or produced more molds, but the real proof is going to be when you fill one up with water and then pour it into the other to find out if they have the same volume.
Different manufacturer or they changed design
Does one have a 7 on the bottom? There’s a made in China look-alike jar with 7s on the bottom.
Yes, this was one of the most disappointing discoveries when I was new to canning.
I had assumed that all quart jars and all pint jars were created equal, so I bought several cases with little thought to my purchases beyond looks. Then I lowered prepared jars into my large All America canner (filled with my hard work) only to find some jars were taller and didn’t “fit” my double-stacked efforts.
You’ll find that many designs, heights, widths, and brands will fall into each measurement category. A good point to occasionally bring up for those new to the process.
As long as the lids and rings fit, the volume difference won’t be enough to matter. It is a pain if you are double stacking your canner.
Same volume..
