Well - without context on specifications and origin of the data i cannot 
properly assess the import plans for it.  We do not even know when this 
data was surveyed.

Overall this approach is highly questionable.  Apparently someone 
working for the City of Ottawa would like to see this data in OSM so 
they make exactly this data in exactly the form they like to see in OSM 
available and lobby for having it imported - without any evidence 
regarding the quality and suitability of the data.

If after the import it becomes evident that there were systematic 
quality problems with the original data - will they accept 
responsibility to fix these problems in OSM then?  Or do they truly 
believe the data being flawless because it was prepared by 'GIS 

Sorry if i come across here overly strong - but the attitude 
communicated so far, which comes across clearly as 'these import plans 
are beyond reproach so any concerns are obviously without basis' is 
quite disrespectful for those who invest time to point out possible 
problems.  As Steward indicated you would be well advised to take the 
Los Angeles buildings import as an example.

Note these are just examples from a few tiles i looked at.  It is very 
likely that the whole data set contains more of such cases.
