Quite a bit of the address data from here seems to be incorrect.

For example: osm.org/node/3582458605

This house should actually be "745 Glen Royal Drive" and the one next it already marked as "745" is actually "735".

Where did you source this import data from exactly?

Went ahead and removed these since there was no reply. In the future please use OHM to map historical features instead of OSM.

Quite a few train lines that no longer exist were added to the map in this changeset, for example way/971353167. Please use OHM to map historical features, those do not belong in OSM.

Whoops, looks like the link was cut off in the commit message. Here is what that was supposed to be:
