Check for the bounds line at the top of the file.

  <bounds minlat="43.1347" minlon="-79.0719" maxlat="43.1752"
maxlon="-79.0197"/>

This did not match what I found with sed.

grep "<node" queenston.osm| sed -e 's/^.*lat="//' | sed -e
's/".*$//'|sort -n|head -1
grep "<node" queenston.osm| sed -e 's/^.*lat="//' | sed -e
's/".*$//'|sort -n|tail -1
grep "<node" queenston.osm| sed -e 's/^.*lon="//' | sed -e
's/".*$//'|sort -n|head -1
grep "<node" queenston.osm| sed -e 's/^.*lon="//' | sed -e
's/".*$//'|sort -n|tail -1

either of these work for you?
