<br>
The former is a problem of each source of data (municipality, city, <br>
province, quango) typically deciding their lawyers have to make minor <br>
tweaks to the wording, which means it's no longer the same license as <br>
any of the approved ones, so must go through the whole LWG approval <br>
process again. The easiest way to work around this in most cases is <br>
getting explicit written consent from the source for use with OSM. See:<br>

<br>
The latter is a problem of buy-in from the community. Large-scale <br>
building imports have been discussed numerous times, with varying <br>
degrees of success (e.g., Toronto's building import seems to be <br>
complete). The most recent of these discussions is, I believe, this one, <br>
which has been silent for a few years now:<br>

<br>
Since then, there has been an address data export from the government of <br>
Canada under an approved license, but I don't believe anyone has <br>
proposed a full data import. The closest I know of is this tool I made <br>
to use the data as a source, not as an automated import (it's currently <br>
targeted at Waterloo Region, but I designed it to be easy to reuse <br>
anywhere covered in the StatCan data):<br>
