Second try, after reworking your steps on Windows 7 and QGIS 2.4 32-bit:

What is written there is almost current.

Normally, you download the map extent, and the bbox coordinates are 
automatically reprojected to WGS84. For Toronto, it should be around:
West: -79.7523
North: 43.8554
East: -79.0002
south: 43.5806
Looking at your second error image, I see "Extent from Layer" for the 
OSM background checked, and West set to -180. That means you want the 
whole world! The overpass API rejects such requests, because it would 
need some GB of traffic. QGIS would not be able to handle that anyway. 
The MB reported is read-only, you can not enter anything there. I got 
291 MB for Toronto.


By the way, you can downgrade to QGIS 2.2, but you can not downgrade the 
plugins.
