Hello, welcome to OpenStreetMap!

First, thanks for updating this area. There aren't many active mappers in Longueuil and Saint-Lambert, so it's always nice when a local joins to help with their area.

A couple of notes:
First of all, the 'name' field for things in the world is intended for the actual name of that thing. 'Sir Charles Condominiums' sounds probably correct, but I suspect the park isn't actually called 'Nouveau parc public de 4 000 m2' :D

If you can get the official name of the park, that would be best--else, it's fine to just leave the name blank when you don't know. It's already marked as a park on the map, and there are better ways to indicate if a park is public or private-access using access tags.

In the future, it also would help if you described the kinds of changes you made in the description when saving. If you've made a bunch of changes and you're not sure how to describe what you did, it's usually a sign that the change should've been broken up into a few smaller ones. Don't worry about it too much either though, it's not a hard rule so much as helpful for other mappers.

Otherwise, your work looks alright at a glance--thank you for contributing!
