1) some links on that page look like this:
<http://canada.justice.gc.ca/eng/notices-avis.html>

Since httrack does not normally go off site, it won't get those. You can add
filter to override those +canada.justice.gc.ca/*

2) some links look like this:
href="/en/ShowFullDoc/cs/C-46//20090310/en"
Since the default is to go down only from the starting url, it won't get
those. You can change expert -> travelmode=up and down or add a filter
+*/en/*

3) The menu on the left is in the form:
href="javascript:doLink('bo-ga:l_XXVIII-gb:s_841')"
FAQ: js only partial support. Httrack can't handle those.

Instead, you can go to the non-frame version:
<http://laws.justice.gc.ca/en/ShowTdm/cs/C-46///en>
enable up/down or add a filter +*/en/*

Or just get the full version in your browser and save/as
