As Canadians across the country complete their 2026 census forms, the national survey is once again generating discussion about privacy, government policy, public planning and civic responsibility.
Conducted every five years by Statistics Canada, the census plays a major role in shaping how governments plan services, allocate funding and understand demographic changes across the country.
Here are five important things Canadians should know about the census and the controversies surrounding it.
The Census in Canada Is More Than 350 Years Old
Canada’s census tradition dates back to 1666, when Jean Talon, administrator of New France, conducted the first population count of the colony.
That early census gathered information such as age, gender, marital status and occupation to help the French colony plan future growth and development.
Following Confederation, Canada conducted its first national census in 1871. The survey asked more than 200 questions related to ancestry, religion, military service, agriculture and education. One of its primary purposes was to determine parliamentary representation based on population distribution.
Today, census data helps governments make decisions related to schools, hospitals, public transit, housing, immigration, labour shortages and infrastructure planning.
The Census Has Faced Political and Privacy Controversies
One of the biggest controversies in modern Canadian census history occurred in 2010, when the Conservative government of Stephen Harper eliminated the mandatory long-form census and replaced it with a voluntary National Household Survey.
Critics argued the change weakened the accuracy and reliability of important demographic data, particularly for smaller communities and language statistics.
The voluntary survey achieved a response rate of 68.6 per cent, compared with more than 93 per cent participation under the mandatory system.
After taking office in 2015, the Liberal government of Justin Trudeau restored the mandatory long-form census, arguing reliable national data was essential for evidence-based policy making.
This year, some Canadians have again expressed privacy concerns online, with a small number publicly refusing to participate as a form of protest against the federal government.
There Can Be Legal Consequences for Refusing to Complete the Census
Under Canada’s Statistics Act, participation in the census is mandatory.
Statistics Canada has stated that reminder letters, phone calls and even in-person visits may be used to encourage participation from households that fail to respond.
Canadians who refuse to complete the census can face fines of up to $500.
Although prosecutions are relatively rare, Statistics Canada referred 47 cases for legal action following the 2016 census and 43 cases after the 2021 census.
Federal officials stress that the purpose of the census is not political surveillance, but rather gathering data that determines funding and services for local communities.
Lockheed Martin’s Past Involvement Sparked Public Backlash
Another major controversy involved the involvement of Lockheed Martin, which supplied software systems used for Canada’s 2006 and 2011 census operations.
The company’s role triggered protests from some Canadians who objected to a defence contractor handling census-related systems.
Several individuals refused to complete the census specifically because of Lockheed Martin’s involvement.
One of the most notable cases involved Toronto peace activist Audrey Tobias, who was prosecuted after refusing to participate in the 2011 census. A judge later dismissed the case and criticized the prosecution.
The controversy intensified national debate about privacy, government outsourcing and public trust in census operations.
Canada Also Conducts a Separate Census of Agriculture
Alongside the national population census, Canada also conducts a Census of Agriculture.
This specialized survey gathers information from farms across the country and has been conducted regularly since 1921.
The agriculture census provides data used by governments, researchers and farm organizations to better understand changes in farming, rural economies, food production and agricultural policy.
Officials say the information helps guide decisions on rural development, food security and support programs for farmers and agricultural communities.
As the 2026 census continues, the debate highlights the balance between privacy concerns and the role national data plays in shaping public policy, funding and services across Canada.
