I'm likely in the same city as nrc.gc.ca, and while I have not
seen a "device fried by a power surge", I have had a surge
protector burned out by lightning down a telephone line. The
attached "device" was not damaged. (Tripp-Lite honored their
warranty and replaced the surge protector.)

Reasonably sophisticated surge protectors (not the $19.95 ones on
the wall at the local big-box store) also tend to filter incoming
so that the "weirdness" associated with transient failures
doesn't get through. Of course, they do not provide UPS capability.
