The Exhibition is a strange place

Official City of Toronto centreline data https://open.toronto.ca/dataset/toronto-centreline-tcl/ indicates the current OSM shape of Nunavut Road is correct and this bit of road under the marker https://www.openstreetmap.org/way/34530521 is not mapped in the centreline data.

TTC shape data e.g. as seen in https://www.nextbus.com/googleMap/?a=ttc&r=29 also has that shape of Nunavut Road bending in a bit to meet Nova Scotia Avenue.

Per the centreline data (and Geobase) the only problem here is the westernmost part of Nunavut Road https://www.openstreetmap.org/way/4165507 should actually be Nova Scotia Avenue.
