Traveling from US to Mexico, but I am Canadian.?

I live in the US and I am traveling to Mexico sometime soon. I don't have my passport anymore because it expired. I don't have my birth abroad certificate because I lost it. All I do have at the moment is my canadian birth certificate and my US drivers license.

Will I be able to travel over the border to Mexico (and back) or will I be denied?

Listen,
I think you may be denied because you don't have enough proof.

OOPs...I see I misinterpreted your question earlier...I thought you were an American citizen, born in Canada...anyway...sorry for that... You should be able to travel to Mexico by LAND with your Canadian birth certificate American drivers' license. And..Canadians do not need a passport to travel to Mexico ( see 2nd site), so you could also fly to Mexico. I don't know how the airline will look at this...be a good idea ro call and verify with them.
