As reported by the National Post, this fine was based on a robocall message that anonymously attacked the Conservative opponent's position on abortion.

[19] In 2011, despite a Conservative majority that saw the Liberals have their worst result ever, they were able to retain the seat by a larger margin as the substantial Green voteshare fell by almost 15 points.

The call for a federal election to be held on October 14, 2008 occurred when Guelph was already in the throes of a by-election scheduled for September 8, which was intended to replace retiring Liberal MP Brenda Chamberlain.

As a result of this, the by-election was cancelled, and the four major candidates running opted to represent their parties again in the federal election.

They included: Frank Valeriote, a local lawyer with thorough community experience who had garnered the Liberal nomination in an upset over Marva Wisdom; Gloria Kovach, a popular city councillor and former President of the Federation of Canadian Municipalities who was controversially handed the Conservative nomination after incumbent nominee Brent Barr was ousted; Tom King, a renowned author and Native rights activist who received several high-profile endorsements after his NDP nomination; and Mike Nagy, a long-time Green Party spokesperson.

Initially in Guelph, optimism ran high that either the NDP, Green Party, or Conservative Party could procure the seat, as many felt that the nominees might benefit from the relative unpopularity of Stéphane Dion's Liberals and the gaffes made by prior Liberal MP Brenda Chamberlain, who had failed to show up to a number of Parliamentary votes and retired before the end of her term in office.

Ultimately, however, Frank Valeriote was able to narrowly garner the seat over star candidate Gloria Kovach, who lost by around three percent and decreased the margin of defeat for her party.
