Thought I'd stop in again and say that I figured it out. My water provider doesn't have control limits on the calcium and magnesium level in the water, so it doesn't appear on the monthly report. I dug around on their page and found a super detailed report, and somewhere on page 26 of 43, I found my stats.
Thanks to all who looked. If anyone else in Edmonton is trying to find their water info, let me know, and I'll show you where I found it.
