Has the 20th century been Canada's century?

I find that preposterous on a Global scale from the clear point that the British Empire most definitely ruled the 19th century. The US was in now way a global power of the 19th century in any way. It wasn't until the massive boost after WWII that the US took point as the major power. The one I've always heard is that the 19th century was the "British" century, the twentieth was the "American" century, and most recently the 21st century will be the "chinese" century.
