How long does it take to complete a postgraduate degree at University of Western Canada?

The University of Western Canada doesn't exist. There's a University of Western Ontario (also known as Western University) and several other universities in Western Canada, but no institution with that exact name.

To answer your question about postgraduate degree length, it varies greatly depending on:

* The specific program: Master's degrees typically take 1-2 years, while doctoral degrees usually take 3-7 years or even longer.

* The university: Even within the same type of degree, different universities may have slightly different program lengths.

* The student: Factors like prior experience, research progress, and the student's pace can influence the completion time.

If you could specify which university in Western Canada you are interested in, I can provide a more accurate answer based on its program offerings.
