Regarding sensitivity sounds that appear to emanate IN MY HOME bother me. I'm OK with distance sounds. During construction I stayed at a 3'rd floor home not far from Bathurst/Bloor. The outside noise didn't bother me. My previous condo was way too noisy with the (3+) tenants always wearing high heel walking/partying late into the evening on the laminate/ceiling. I didn't hear noise from adjacent neighbors. At my town I can hear the (one guy) neighbor walking on floors/stairs, doors, chairs, music. Additionally I'm finding my town is too big for me @ 1750 sq ft, I'm not crazy about stairs, cutting the lawn and I've always lived downtown previously.
I have a buddy who just downsized and bought a 10-year old penthouse in South Etobicoke. He is going to let me know how quiet the unit is so I can get an idea of the noise level.
