the actual g7 is:

1. united states
2. china
3. japan
4. germany
5. india
6. france
7. united kingdom

the countries that don't belong there are canada and italy. but, italy can get in with the 8th seed if you want to be more generous.

8. italy

is canada next? no. it's brazil.

9. brazil

then canada.

10. canada
11. russia

however, russia is growing at a much faster rate than we are and will pass us within a year or two.

so, keep trying to exclude others, canada - you're just ensuring your own irrelevance, in the long run.
