It appears that you realigned a large number of objects in this changeset. Please check if imagery is offset from actual position by using a GPS before making these sorts of changesets over a large area.

Hi can you please add the bus stops in the correct locations instead of deleting them?

This edit is incorrect and has been reverted. Highway 418 is not closed to traffic.

These "local traffic only roads" are temporary, and most drivers are ignoring them. Do these belong in OSM?

This edit has been reverted. Please do not add fictitious mountains and deserts to OSM.

You do not need to add is_in for minor features like street lamps

I am pretty sure that the Highway 12 designation goes a bit south of Highway 407 and that there is a Highway 12 ends sign posted a bit south of there (or was before the 407 opened). Has this changed?

I have used the "Mapbox Satellite" imagery to improve the accuracy of this playground. I recommend that you use this imagery in the future as it is from 2015 and is the newest imagery available in York Region and Toronto.

Why did you remove this bridge?

Not yet. The highway will open at approximately 2am on June 20. This changeset has been reverted. Please do not change it back until the highway is officially open

Does this traffic detector actually exist?

You can still u-turn eastbound because there is no sign saying that you can't. This no left turn relation is not needed because the oneway=yes on the offramp from the 400 ramp implies this.

There is no castle here.

These bins are both garbage and recycling. I am not sure how to tag this. I don't think amenity=recycling is correct

Please refrain from making edits like this. TD has started to remove the "Canada Trust" name from the signs of certain bank branches, I think that they may discontinue using the "Canada Trust" name in the future, so some branches are only called "TD" now. (Although banks that are only named "Canada Trust" are certainly incorrect because they changed name a long time ago when TD merged with Canada Trust). I would suggest that you only make edits like this if you have surveyed the location or can see the bank's sign on Mapillary.

Please do not make mechanical edits (edits of a large number of objects over a large area at once) unless they are discussed. While this edit appears to be correct, an administrator may choose to revert this edit because it is against OSM policy.

I am pretty sure this is "Deloitte".

Best Buy was already on the map. I have removed the duplicate marker.

Why is the future school inside the park?

I changed the school to landuse=construction. I presume that the school is being rebuilt?
