According to Statistics Canada’s job vacancies report, vacancies for software engineers and designers increased by 115 per cent between Q2 of 2021 and Q2 of 2022 [1], and vacancies for computer and information systems managers rose about 36 per cent over the same period [2]. 

You can find computer science jobs in nearly every industry, including health care, business, finance, entertainment, and government. Anyone interested in these careers might benefit from the expertise and enhanced job prospects of earning a master's in computer science.

Discover more about this field, what a master's in computer science is all about, and the types of jobs you can pursue once you've earned this degree.  

What is computer science?

Computer science includes computing, software development, memory management, hardware, networking, and internet communications. Computer science has shifted from studying hardware to studying software and developing programs, writing code, and managing systems. 

Computer science students use their knowledge to develop solutions to technical problems, create programs for clients, or design applications for work or entertainment.  

What is covered in a computer science master's program?

With a Master of Science in computer science, you'll learn advanced concepts in computer science topics, such as software design, computer language theory, programming, and computer architecture. 

If you're already in the computer science field, you might pursue this degree to advance in your profession or become a more competitive job candidate. If you're pivoting into computer science from another area, you could leverage your master's degree to familiarize yourself and build confidence in your new industry.

Three types of computer science master’s programs exist in Canada: the Master of Applied Computer Sciences (MACS), Master of Computer Science and Engineering (M.Eng), and the Master of Computer Science (MsC) [3]. While curriculum varies by program, key concepts you can expect to learn include:

• Software development

• Computer systems

• Data structures

• Algorithms and computation

• Machine learning

• Data visualization

• Natural language processing

• Numerical analysis

• Cloud computing

• Internet of Things (IoT)

• Software, information, and network security

• Software testing

• Cryptography

Concentrations

You will also likely have the opportunity to specialize in an area of your choice, and your coursework will focus on this area. Possible concentrations include:

• Cybersecurity

• Big data

• Data science

• Artificial intelligence (AI)

• Systems and software

• Games

• Robotics 

Entry requirements for a computer science master's

Many computer science master's programs require a cumulative GPA of 3.0 or higher. Some programs may have a lower GPA requirement. Most programs also recommend a bachelor's degree in a related field. Job experience could be helpful, but it's not always necessary. You may need a letter of recommendation as well. 

Many universities offer master's programs for computer science, so you're likely to find a program that suits you and an environment where you can learn and grow.

How long does a master's in computer science take to complete?

Most computer science master's degrees take 1.5 to 2 years, depending on your path and program. Part-time and online programs can give you more flexible options to earn your degree while you work or have other responsibilities. However, it may take longer to complete your degree, depending on your time commitment.

Do I need a master's in computer science to work as a computer scientist?

If you’re pursuing an entry-level position as a computer scientist, you may not need a master's degree. Usually, a bachelor's in computer science or a related field will suffice. However, if you're interested in more senior or leadership positions, those jobs may require a master's degree. 

What can I do with a master's in computer science?
