Transit via USA

[immihelp]

Hi,
I am holding an Indian Passport with Canadian Work Permit. Can I fly from toronto(canada) to new delhi(india) via New York? I have to stay at New York airport for about 2 Hrs.
What kind of visa do I need? I already have a valid B1/B2 visa. Is this visa enough for my transit purpose? Any help will be highly appreciated.
Regards,

That's enough. No separate visa required.
