2000 election
A few weeks after Day entered the House of Commons, Jean Chrétien called a snap election for November 27, 2000, which would not give the newly formed Canadian Alliance time to consolidate itself. Nonetheless, the new party went into the election with high hopes, as Day was expected to appeal far more to the crucial Ontario voters than his predecessors.
There were few, if any, important issues when the election was called; nonetheless, the Liberals frequently alleged that Day had a hidden agenda, identifying Day with the Christian right, and drawing attention to his past comments about homosexuality and abortion.
In an interview published in the alternative weekly Montreal Mirror on June 8, Day addressed some of the perceptions that he was homophobic. He began by denying that he had ever referred to homosexuality as a "mental disorder". He acknowledged having gay staff working on his campaign: "First of all, as far as my campaign, I don't ask people if they're homosexual, lesbian or heterosexual. People who are working on my campaign are doing so because they believe in me. That doesn't mean that they necessarily agree 100 per cent with everything I believe. But in principle they're saying we think you can take this Alliance to the next step and we think you'd be good for Canada. So I don't ask. Nobody has to pass a sex test to be on this campaign." But the statement that made headlines in newspapers across the country was Day's acknowledgment that he would indeed consider using the Notwithstanding Clause to block a Supreme Court decision legalizing same-sex marriage, then a distinct possibility that was unnerving many social conservatives. After being pressed by journalist Matthew Hays on the Notwithstanding Clause question, Day replied "Yes, and the reason I say that is because such a significant number of constituents would reflect concern on that and would want the discussion. The Alberta position on this is that the definition of marriage changing would allow for the use of the Notwithstanding Clause. That's because the sense of the elected officials in Alberta is that the people would be significantly motivated on that issue."
Liberal activist Warren Kinsella mocked Day's belief in young Earth creationism by pulling out a Barney doll during a television interview and stating that "this was the only dinosaur ever to be on Earth with humans". Media covering the Day campaign bus, nicknamed "Prayer Force One", hummed The Flintstones theme song to mock the idea that humans and dinosaurs co-existed.
During the 2000 election, the CBC ran an extended documentary purporting to review Day's religious beliefs. In this documentary the CBC interviewed Professor Pliny Hayes, Chair of the Department of Natural Sciences at Red Deer College, who reported that Day said in a speech at the college that there is scientific proof that the world is about 6,000 years old and that early man co-existed with dinosaurs. Day filed a complaint with the CBC for the fact that he was at no time asked for comment on the matter.
When subsequently asked by reporters about his beliefs, Day said he didn't think his beliefs "should be used in any kind of detrimental way in an election campaign." Day's spokesman Phil Von Finckenstein said the Alliance believes that other theories of creation should be taught alongside evolution in schools, but he also recognizes education is a provincial jurisdiction.
The Alliance's direct democracy proposals, which would have required a referendum on any proposal supported by a petition signed by three per cent of Canadian voters, were also frequently targeted as a suggestion of a hidden agenda. Some asserted that "special interest" groups would use the low requirements to put contentious subjects to a national referendum. Day himself never did support the threshold, explaining that he would need to consult with Canadians over what the threshold should be. The proposal was satirized by Rick Mercer of This Hour Has 22 Minutes, where he proposed a national petition for a referendum to demand that Day change his first name to Doris, which reached the threshold advocated by The Alliance.
Another gaffe took place when the Day campaign used the hit single "Ordinary Day" by Great Big Sea at a rally without permission. The band demanded that Day's campaign cease using the song for campaigning purposes.
Day was also a victim of an incident during the election. When making a "grand entrance" for a speech at Conestoga College, activist Julian Ichim splashed him with two litres of chocolate milk from the front of the stage, saying he did it to protest Day's "homophobic, anti-immigrant and anti-poor agenda". Afterward, again on This Hour Has 22 Minutes, actress Mary Walsh jokingly offered Day chocolate milk, saying: "All they had was homo, and I knew [Day] wouldn't like that."
Day stumbled during two campaign appearances in the first week. A photo-op at a technology firm meant to illustrate a "brain drain" to the US was undermined when the owner reported that he had moved to Canada from the United States eight years earlier. The next day, at Niagara Falls, Day remarked that Canadian jobs were flowing south "just like the Niagara River", when in fact the river flows north. In mid-campaign, the Alliance candidate in Winnipeg South Centre, Betty Granger, was quoted as voicing concerns about an "Asian invasion" in Canada. And in the televised leaders' debate, Day held up a handwritten sign saying "NO 2-TIER HEALTHCARE" in large letters to counter a newspaper headline in The Globe and Mail earlier in the campaign. As props were against the rules, he claimed it was his briefing notes. Progressive Conservative leader Joe Clark retorted, "Mr. Day appears to be running for office as some kind of game show host." The debate went poorly for Day, with the Toronto Star and The Globe and Mail describing him as "the big loser" of the night.
At one point, the Alliance was at 30.5 per cent in the polls, and some thought they could win a minority government. On election night, the Alliance increased their seats over Reform totals from 60 to 66 and kept Reform's strong representation in western Canada, but the hoped-for breakthrough in Ontario did not occur, with the party electing just two MPs in that province. However, the Alliance increased their overall vote totals by over one million and reduced the Progressive Conservatives to 12 seats in the House of Commons. The Liberals' attacks on Day ended up decimating the NDP and Progressive Conservatives, as many voters who would otherwise have supported those parties voted strategically for the Liberals to prevent an Alliance victory.
