Nova Scotia
Most Conservative poll
Argyle went surprisingly Tory despite the Liberal candidate being the Acadian.

Least NDP poll
Sydney-Victoria, 162 (2.44%) This poll is probably another error. In fact, I think in reality the NDP won the poll, if it was a simple swap between the Greens and NDP. The Greens "won" this poll with 41% of the vote while they were in the single digits in surrounding polls. The NDP won a few and did well in some surrounding polls indicating that this is probably an error.
Argyle is also very strongly PC at a provincial level (from memory, safest PC seat? I could be wrong, though). You're probably right about that NDP result being a data swap, judging from the provincial results again - the NDP holds a few seats around Sydney, and I think by very safe margins in some cases.
