Prime Minister Justin Trudeau and Conservative Party Leader Andrew Scheer have publicly said that the October federal election campaign will be one of the nastiest in Canadian history. It appears both parties are getting ready to fight fire with fire. If true, it would be a disastrous strategy; not only for both political parties, but also for the social fabric of our Canadian society. Each party leader has accused the other of planning on being negative and both the Liberals and Conservatives have vowed to run positive campaigns. It remains to be seen who will break the vow. Unofficially, the campaign for the Oct. 21 election is already underway and will get into full swing once the House adjourns next month. It’s also unclear yet which party, if any, will take the high road, choosing not to go negative. But all national parties must remember the 2015 election campaign in which then-prime minister Stephen Harper played with fire by using religious, racial, and cultural issues, such as the niqab issue, or starting the snitch line to report on barbaric cultural issues, and how he faced the consequences. Mr. Trudeau's Liberals did not resort to negative campaigning and reaped the benefits as Canadians were sick and tired of political parties using race and culture for political gains. Canada is a country full of immigrants from different cultural, social, and religious backgrounds and is a model for the rest of the world. By resorting to divisive campaign rhetoric, party leaders would undermine Canada's social fabric which Canadians will not let go unpunished at the polls. If anyone has any doubt, they can look at the last election when Liberals went from the third-place party to winning a majority government. It is hoped that even though the Liberal Party and Mr. Trudeau’s popularity have taken hits as a result of unforced errors, the Liberals will still take the high road. It should be clear to Mr. Trudeau that resorting to cheap divisive tactics on immigration, race, culture, or any other issue won't help him. On the Conservative side, as pointed out by Maclean’s magazine recently, the “Conservative leader has left himself open to charges of intolerance in his party,” which “could be the biggest, ugliest issue in the coming election.” Although Mr. Scheer and other Conservatives have vehemently denied this charge, in politics, as they say, perception is reality. Denying it is not enough and would require concrete steps to address this issue. Mr. Scheer and other senior Conservatives must do everything they can to address this issue, now. If both parties, however, do stay away from divisive campaign tactics then it will open up opportunities for the NDP and the Green Party. The recent provincial election results prove that Canadians are not shy anymore about throwing the established political parties out, and replacing them with third-place and fourth-place parties, albeit, with short electoral history. By running a constructive and positive campaign, the NDP and the Green Party can reap the benefits.
