I was put on that list immediately after I visited Ukraine with Prime Minister Harper when he went to show support for Ukraine right after the Maidan revolution and the fleeing of President Yanukovych. At that point, Prime Minister Harper was advocating for Russia to be excluded from the G8, and was successful. After that decision was made, out of spite, President Putin then created that list of 13 people to put on the sanctions list.
On October 23rd, 2017. See this statement in context.
