Canada isn't an education superpower. The silly international ranking of kids' test taking abilities is meaningless.
Real education superpowers are those with top universities which in turn produce economic gains/growth/etc.
If canada was a true economic superpower, we'd see them producing Google, Facebook, Microsoft, etc.
Frankly, there is only 1 education superpower - the US. Go check a list of top 100 universities. It's almost entirely US colleges. Britain is the next far distant competitor. The only other nation who may challenge the US to become an education superpower in the future is china as they are building tons of universities. This is something we did in the US in the 1800s. Build a incredible number of universities as our economy grew. The only question is whether china will be able to match our quality because they are going to surpass our quantity by a large margin.

Also, if the BBC journalist did any bit of research, they would know that Canada's "150th anniversary" is fake propaganda itself. Canada isn't 150 years old. They gained their independence in 1983.
