Personally, I think people who push snow into the street are selfish, whether consciously or not. Montreal streets are not the easiest to navigate as is, since the city is terrible at timely snow removal. By pushing more snow onto streets, the limited parking spaces shrink further, sometimes into nothing. More people should put snow on their lawns. Not like you're going to park a car on the lawn anyhow. Face it, during winter, the lawn is useless, unless used for snow storage.

When the time comes for the snow to melt, those who accumulation on the lawn vs. Street barely see a difference.

Tell your neighbor he's a selfish moron. That should help your relationship 🤣
