What you can consider, which is code-compliant in the US and Canada and
a safety benefit, is to have the ungrounded outlets replaced with GFCI
receptacles. This does not provide ground but will protect against a
lot of what can go wrong. GFCI's come with stickers that say "no
equipment ground" that you put on the faceplace when you do this.

Are there any down sides to replace all the outlets in one's home with
GFCI's? Would refrigerators cause it to trip under normal operations?

Thanks.
