Entering Canada DUI Pretrial Diversion, charges dropped

[Patsfan]

I was arrested in May 2010, for DUI (non accident) in the State of Connecticut. Being my first criminal offense, at the arraignment no please was entered, and the state offered me a pretrial diversionary program, which consisted of alcohol education which I have successfully completed. The state will be dropping all charges at the end of the month. Again, no plea was ever entered, and charges will be dropped, so there is no conviction.

Can I enter Canada, or am I still considered criminal inadmissible?

thanks
