If your parents are from another country than you hold citizenship in that country as well. For this purpose you can claim that you are NOT Canadian citizen.

Your best chances would be to sign up for the "Green Card Lottery" which they hold once a year.

I just checkied it out and canadian citzens cant register.

LJDriver is correct. Even if you are born in Canada there are 2 other ways you could be accepted... read on.

The lottery is called DV lottery meaning Diversity Visa lottery and FYI it's too late to apply for 2006 one but probably Nov 05 you can apply for 2007 and don't forget to check if the country your spouse or parents are from are eligible before applying in Nov as the list changes every year.

"REQUIREMENTS FOR ENTRY

Applicant must be a native of one of the countries listed beginning on page 13. See “List Of Countries By Region Whose Natives Qualify.”

Native of a country whose natives qualify: In most cases this means the country in which the applicant was born. However, there are two other ways a person may be able to qualify. First, if a person was born in a country whose natives are ineligible but his/her spouse was born in a country whose natives are eligible, such person can claim the spouse's country of birth provided both the applicant and spouse are issued visas and enter the U.S. simultaneously. Second, if a person was born in a country whose natives are ineligible, but neither of his/her parents was born there or resided there at the time of his/her birth, such person may claim nativity in one of the parents' country of birth if it is a country whose natives qualify for the DV-2006 program.
Applicant must meet either the education or training requirement of the DV program.

Education or Training: An applicant must have EITHER a high school education or its equivalent, defined as successful completion of a 12-year course of elementary and secondary education; OR two years of work experience within the past five years in an occupation requiring at least two years of training or experience to perform. The U.S. Department of Labor's O*Net OnLine database will be used to determine qualifying work experience. "

Thank you 350TT. For those that didn't read through 350TT's reference above here it is:
