2019 Election - The reason behind the recommendation

To come up with a recommendation I used:

• Publicly available riding-level opinion polls data. Latest polls take precedence as the long as the poll result is higher than the margin of error
• 2015 election results, if supported by available opinion polls
• When polling data conflicts with 2015 election results, I review previous election results (2004, 2006, 2008 and 2011) for the riding voting trend and the reason behind the conflict.

If the chart does not explain the recommendation, please check the "Comments" field.
