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.

Please tag parking lots as amenity=parking. I have corrected the parking lot you added near Drewry Avenue and Yonge Street.

The parking lot is not "SITE". I have undone this edit. Do you mean that a building is under construction on this former parking lot?

This pedestrian area is not Roy Thomson Hall. Roy Thomson Hall is the building to the east. I have fixed this.

Please use 7-Eleven not 7-11. I have corrected this.

You accidentally created a wiggle in St. Dunstan Drive that does not actually exist. I have corrected this. Please see <osm.wiki/Beginners%27_Guide> for information on how to contribute to OpenStreetMap. Thank you for contributing to OpenStreetMap.

The path should not be connected to the park outline. I have corrected this.

Please add the name of convenience store.
