This document summarizes the results of a survey of Canadian MPs and former MPs regarding their use of online communication tools. Some key findings include: - Four in ten current MPs share responsibility for handling constituent correspondence with their staff. Almost all collect personal information from constituents. - MPs have partially embraced social media but prefer email for hearing from constituents. Personal forms of communication like meetings and letters are given more weight than non-personal forms when motivating MPs to act. - Large numbers of communications can influence MPs, but personal contact is most effective at changing minds and priorities. The survey findings provide lessons for groups to take integrated, personalized approaches when campaigning to influence MPs.
