The moment you decide to move to a different country for beginning a new life, you must have thought of different countries. You need to compare a lot of factors before settling down to a particular country because there you are going to spend a large part of your life. When it comes to getting a permanent residency visa, both Canada and Australia are considered as the most preferred immigration destination.
Standard and Cost of Living:
Both these countries offer a quality standard of living, but when it comes to living expenses, then Australia is more expensive than Canada. Housing tax in Australia is higher than in Canada. It would be better to get a Canada permanent resident visa if the expense is a concern for you.
The immigration process is much easier in Canada. Except for language fluency they don’t focus much on other things.
As both these countries are dependent on mining and resources, it would be hard to say which one offers better job opportunities. One the one hand, Canada has a better manufacturing base, while Australia is known for US IT firms. Get Australia permanent resident visa if you are looking for white collar job, for blue collar jobs, go for Canada.
