2.2 Do you provide training?

Statistics Canada gives high priority to human resource training and development. Employees are encouraged to develop their interests and are supported throughout their career. Statistics Canada offers a complete, well-organized development program in both official languages.

Our statistical training program is large, varied and includes courses or other learning activities of high quality. In the current modernization context at Statistics Canada, mathematical-statisticians must maintain and develop their capacities related to traditional survey methods, while making room for leading-edge methods, data integration and data science.

One of the goals of our training and development program is to build a culture of productive learning. The courses in the classic classroom format are only one element among many of our training tools, that also include self-directed, informal, and by experience training. Seminars, Conferences, or the possibility to pursue university education.

3.0 The work of mathematical statisticians

3.1 What do you expect when someone starts working at Statistics Canada?

On arrival, you will work closely with a more experienced mathematical statistician. He or she will assign your tasks, advise you on technical and professional matters, supervise your training and guide you in your career plan.

3.2 What are the tasks of a mathematical statistician?

Mathematical Statisticians apply, adapt and develop mathematical, statistical or survey methods to practical problems. They explore and adopt sophisticated methods to integrate and transform alternate data sources into statistical information. Their work is crucial to Statistics Canada.

As a mathematical statistician, your main duties will consist of designing, implementing and evaluating statistical methods related to the production of official statistics. This could include work on surveys, work on research projects in various areas related to statistical methods, or work on new methods such as integrating data from a variety of existing sources or adopting new methods to analyze data. Mathematical Statisticians can also be involved in projects related to the combination of classic and leading edge statistical methods, including experimentation with machine learning, artificial intelligence techniques, non-probabilistic sampling, micro simulation and modeled/synthetic data. Mathematical Statisticians face a wide range of theoretical and practical statistical challenges!

The primary role of most of the Mathematical Statisticians is to provide methodological services for Statistics Canada projects. This service is oriented to our internal clients and requires mathematical statisticians to acquire some knowledge of the client area in order to determine and meet its methodological needs.

The work of a mathematical statistician is highly diversified and requires creativity and adaptability.

3.3 Do you have research positions in the mathematical statistician group?

To design and implement effective, scientifically sound methodology, a mathematical statistician must always maintain a good balance of skills in analytical and empirical research and operational work. The majority of mathematical statisticians provide survey methodological support services while some of them are also involved in research. Initially, research could make up only a small part of the duties of a mathematical statistician. However, it could become a major part of his/her duties depending on his/her experience and interests.

3.4 Do you work in teams/groups?

Statistics Canada projects are normally developed through multidisciplinary project teams. Such teams consist of experts from various areas: subject-matter (e.g., economists, sociologists, geographers), survey operations, systems development and survey methodology (mathematical statisticians).

3.5 In what language do you work at Statistics Canada?

At Statistics Canada, you will work with colleagues who speak English and/or French. All managers at Statistics Canada are expected to be able to work in both official languages and all staff are encouraged to become bilingual and make use of both English and French in all aspects of their work. However, bilingualism is not a criterion for recruitment. Training in the other official language (in-house courses and courses given by public or private training institutions) is part of the Recruitment and Development Program.

4.0 The workplace

4.1 If I am hired as a mathematical statistician at Statistics Canada, where will I work?

In the past, all mathematical statistician positions were located at Statistics Canada's head office in Ottawa. Currently, mathematical statisticians work from home due to the pandemic, with some employees working in various places across Canada. It is currently uncertain if employees will be required to be located in Ottawa at a future date.

4.2 Do you pay for the move?

If you are required to move, expenses related to relocation are usually paid by Statistics Canada.
