Am I prohibited from visiting Canada?

I'm pretty sure restriction is limited to felony charges, not misdemeanors. Try this link http://www.cbsa-asfc.gc.ca/menu-e.html

You'll probably clear customs without a problem. Unless you get pulled aside for secondary inspection and then they'll run your criminal history and you won't be allowed in. Give it a shot. It'll be an adventure.

As far as I know, if you have any type of criminal record you won't be allowed to cross the border.

First off you have a record so that means NO entry to Canada. It doesn't matter what you did but you broke the law. That means you can't abide by the laws of your country why would Canada believe you can abide by our laws? First thing you should do is get in touch with the Canadian consulate and tell them what you would like to do. They will be able to tell you how you can come to Canada the right way. If you get caught crossing the border you will be arrested and could spend some time in the local jail. Then you would have a hearing and most likely be told that you could never come back to Canada. Remember ignorance is no excuse. Do yourself a favour and make sure you come to Canada the right way and enjoy your trip as a free man and not one travelling in an enforcement vehicle.

I don't know officially if you are prohibited or not from entering my country but I sure hope so. We don't need people like you if you still haven't learned your lesson and still consider public intoxication a minor crime and adding insult to injury, by mentionning that officially you can drink in all provinces....... Stay home and sober up !

I don't think you will have a problem. Can you imagine them checking every person that crosses the border for their criminal record.

i dont have a problem going into canada,they just dont want to let me back into the usa...i dont have a clue why...no past record of any kind..i guess they want to check my trunk for marijuana.which i havent done in 20 years

If they were misdemeaners and not felonies, you can get into Canada. You may want to ensure that you probation or court restrictions placed on you as punishment don't prevent you from leaving the US or your state.

No. You are not allowed into Canada. After your charge is significantly stale and you don't have any other charges they will let you in. But that is after 5 to 10 years. As explained in my link. Yours is this year, so not even close. Canada mostly cares if you have a criminal record, we don't care if it is a Felony or a Misdemeanor - those don't mean anything here. (Other than in the 10 year thing) But what they are checking of you is that you didn't follow the laws of your home country. It is possible some country's laws are found to be very unreasonable and you can get it waved. The same mentality could be used here, you visit and break Canadian laws - like say carrying a hand gun, and your argument would be it isn't a crime at home? And public intoxication could get you charged here too. And illegal possession - doubt it matters that the age is different. Sorry, this is starting to sound preachy, it isn't the intent, I am trying to show the principles and the regulations. It is waved if you were under 18 when you committed the offenses. Now "could" you make it in. Probably, but it is at the risk of getting caught and messing up future entry. Also if you travel to the boarder with friends and you don't get in, that would be embarrassing. They typically ask about criminal records and then focus on DUI's. If you lie and they catch you, it only gets worse. So here are the links that you can verify the regulations for yourself.
