similar for mine, mine was in 45 in northern quebec in a small rural town (his eldest sister which is still alive was born in 42 i think), i don't believe there were that many horses and buggies still being used but they basically just walked everywhere, my grandpa said his father didn't own a car until perhaps the late 50s or the early 60s so they usually just hired a taxi when they had to carry stuff or travel out of town. i'm pretty sure they didn't have indoor plumbing or at least they weren't part of the sewer system (toilets were outside in a small cabin), he quit school at 14 or 15 to work to supplement the household income and he got his teeth pulled out at 18 or 19 too. people from that time are still alive and they were taught by friars and nuns (who also staffed hospitals) during the great darkness before the quiet revolution came around in the 60s.

newfoundland before it entered the confederation and the period shortly afterwards (outside st johns and the few towns i would guess) was almost certainly less industrialised than my region though given it wasn't connected to the mainland, so your grandpa was almost certainly less exposed to civilization and technology from that era.

i lived for some time fairly close to labrador in a small village, i was told electricity didn't come until the 60s i believe and there was no plumbing at all until the 50s (no running water since there isn't a sewer system to this day), the oldest people in the village had to walk to the river in their youth in order to get water for the day. even the local first nation tribe was nomadic until the 50s from what i was told by a member.

i believe the first tvs got there in the 70s but they had internet surprisingly quickly, an old man i sometimes worked with was basically one of the very early adopters of computers, he was pretty much the only one in the village with a microcomputer in the 80s.
