This is largely due to the fact that people are dissatisfied with their views being underrepresented in the House of Commons. For example in the 1993 federal election, "the separatist Bloc Quebecois (BQ) won 72% of the seats in Quebec with the support of only 49.2% of Quebec voters "(Hiemstra and Jensen, 296). This trend exists across the nation. In British Columbia's 1991 election, "NDP popular support dropped to 41% of the vote, yet they took 68% of the seats and formed the new government "(Hiemstra and Jansen, 298). Evidently, the percentage composition of the House and legislature is tragically skewed from the actual percentage of people who supported the elected representative. This causes MPs and political parties to pay heed only to the wishes of the majority and undermine the concerns of the minority. Canadian views and attitudes are diverse and require representation for each of their varied needs. An absence of this democratic right makes the Canadian government conducive to ineffectiveness. .
Another disadvantage of the single member plurality electoral system is its tendency to hinder national unity. Party preferences seem to be divided across Canada. .
The Canadian Alliance garners most support in the West, as opposed to Atlantic Canada where the NDP and the Progressive Conservatives have marked their territory. The Liberals have successfully captured the province of Ontario. SMP represents a limited cross-section of society because of its inability to produce a multi-party coalition government, which would adhere to all of the regional and linguistic parties across Canada. Henry Milner, Professor of Vanier College, maintains, "where the SMP system has produced majority governments, the tendency of the system to polarize rather than promote compromise has not necessarily served Canada well "(Milner, 43). An effective government can only be achieved through compromise and teamwork.
