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?

Presumably "Curch" is a typo?

You did not place the Honda parts shop in the right place. It probably should be where "Parkway Honda" is.

You can't copy from that website without specifically being given permission.

The outline of Highway 407 East and Highway 412 is based on Landsat images I believe. It is very rough but it is all we have until the highway opens. It is supposed to open at the end of the year.

This is not the correct way to tag a pedestrian crossing. There was already a pedestrian crossing tagged here, this has been fixed now.

The police station was on the map already.

http://www.407eastphase1.ca/wp-content/gallery/segment-b-1/pic3-structure_b1_corrected.jpg is a copyrighted source, so unfortunately you cannot use this in OSM. This edit has been reverted.

Is the full name of the school really "R. A. Riddell"?

Operator of trail presumably should include City of Brampton

Please tag pharmacies as amenity=pharmacy

Please enter the opening_hours as shown on <osm.wiki/Key:opening%20hours>. What days of the week is the RBC open? Is it open only Monday-Friday or is it open on weekends as well?

Please use amenity=bench for benches.

You made a mistake in editing the railway tracks around Union Station, so unfortunately I have had to revert this edit.
