at this location:

http://www.openstreetmap.org/?lat=52.27373&lon=-113.81211&zoom=17&layers=C

and here's the corresonding area on Google maps:

https://maps.google.com/maps?ll=52.274979,-113.808993&spn=0.004352,0.01075&t=m&z=17

... you can see that many mapped roads end abruptly and a few are unconnected to any other roads whatsoever. Since this is my hometown, I know the mapping is inaccurate and has been changed in the last few months, since I used to see these roads on OSM.

But I don't suspect vandalism or inept local revisions erasing major roads. Rather, I think someone has made some higher-level changes which inadvertently erased mapping in this area.

For this reason, I'm reluctant to remap the erased roads because (a) it's too labor intensive and (b) the same thing could happen again.

Can anyone help restore the lost mapping?

The roads in question likely fell victim to OSM's license change, which made it necessary to delete data contributed by people who have not agreed to the new license. See this OSM Inspector view to learn what has been deleted in your area (stuff shown in red):

http://tools.geofabrik.de/osmi/?view=redactionbot&lon=-113.81211&lat=52.27373&zoom=15

Sadly, you will have to re-create that data because the original creator(s) did not allow us to continue using it.

If, as your name suggests you have a GPS it would be good to get a few more traces of the area and upload them these can then be used to check Bing alignment. Others could then map in some of the roads and streets, but local knowledge, maybe yours, will be required to name the streets. You probably know that we can't use Google and other copyrighted data to do this. With a bit of practice remapping these roads will not be hard or too labour intensive. The redaction of the roads is unlikely to occur again, once in eight years?? of OSM so please don't let that stop you. good luck I'm sure others will help.
