Canada the Good considers more than five hundred years of debates and regulation that have conditioned Canadians' attitudes towards certain vices. Early European settlers implemented a Christian moral order that regulated sexual behaviour, gambling, and drinking. Later, some transgressions were diagnosed as health issues that required treatment. Those who refused the label of illness argued that behaviours formerly deemed as vices were within the range of normal human behaviour. This historical synthesis demonstrates how moral regulation has changed over time, how it has shaped Canadians' lives, why some debates have almost disappeared and others persist, and why some individuals and groups have felt empowered to tackle collective social issues.
