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
