The plan was to stage a "snake march" to close down the main thoroughfares in the downtown core, in order to prevent corporate offices from functioning and to disrupt the lower-level G8 meetings.

By late morning, some 5,000 protesters had converged on the downtown core,[citation needed] and the snake march came to an end.

[citation needed] The zone system was developed for the Summit of the Americas demonstrations in Quebec City the previous year.

The red zone was an area for groups intending to practice active civil disobedience with a high risk of arrest.

The yellow zone was for demonstrators taking part in non-permitted events that carried a slight risk of arrest.

The march took over two intersections outside of large corporate headquarters and held them while some protesters played a game of soccer in the street and others graffitied the area.
