Mark,
CSA have standards for over and under voltage, Typical no more that 3%
over and 5% under if memory serves me.
This might help (

)
The power companies here in Alberta are generally good about fixing
problems with line regulation.
There can be problems with industrial areas and big welders or motors
staring as I am sure you know.
I am sure they do not want the bill for replacing equipment that was
subjected to over voltage.
On UPSs: I am sure you are aware that may of them are not TRUE sine wave
so the DMM may not read correctly.
Mitch,
Snip
