How has the 21st century contributed to change that can still be felt amongst citizens today in Canada and on a global scale?

Answer 1

We are still in the first quarter of the 21st century so cannot know the answer.

Of course we can speculate. The 21st century saw a major shift in global economic, military and political power. The political instabilities in Canada combined with our inability to revise our Constitution to meet changing needs resulted in a New Confederation. Western Canadians, most of them of Asian descent the result of early 21st century Immigration, set a new, more international course that saw them end the traditional transfer of wealth to Eastern Canada and the USA.

The loss of sole access to Canadian resources by the American Empire has contributed to their decline and led to the actions they have taken. Actions that have been felt and continue to be felt on a Global scale.
