I just did a ground survey of the area in Kitchener, and I saw no evidence of any ongoing highway construction. For planned highways, we have a tag for that: https://wiki.openstreetmap.org/wiki/Tag:highway=proposed
A tag I suspect you're aware of, since you actively removed it. As is, the existence of the highway isn't verifiable on the ground, so even the highway=proposed version is subject to deletion anyway; mapping it as active construction is unambiguously incorrect, as the first sentence of the highway=construction tag description would indicate.

I'm also curious why you decided to map it as construction at all, since every online source I've found says that construction is no closer to starting than it was 15 years ago, with no contracts approved or even currently being sought. You should always fill out the source field when making edits, so that other mappers can tell if you have some insight they don't.

I'm going to revert all the edits you've made around Kitchener. With the above in mind, are there other edits you would like me to revert as well?
