This matter is addressed in the regulations of the federal Official Languages Act. The exact definition of “significant demand” is determined by population census data. For example, in larger urban centres, significant demand is reached when the minority population is at least 5,000. In smaller town and rural regions, bilingual services are required if the minority population reaches at least 500 people and represent 5% of the total population. The regulations addressing the concept of the “nature of the office” require bilingualism for standardized announcements and signage regarding the health, safety and security of the public, national parks, and all Canadian diplomatic missions on foreign soil.
