Although Canadian governments alternate between various liberal and conservative parties depending on the political climate, in general all of Canada's political parties have relatively centrist positions on hot-button issues such as women's and LGBT rights, environmental concerns and immigration, which are sometimes very controversial. in other democratic countries. Canadians also have trust and respect for the political system and government agencies. Although scandals occasionally arise, they tend to be fairly benign and there are few cases of widespread corruption, fraud, or distrust of the government. Canada's political campaigns are also short and inexpensive for taxpayers compared to other democratic countries. Even at the national level, political campaigns rarely last more than a few months.
