Are you asking about leaving Canada or entering the US?
I'm wondering if I can enter the US before my court date
I will move this to the US law list then.
I am sorry that this has happened to you. I have experience with Canadian criminal charges and the resultant issues with US Criminal Inadmissibility so I'll give you some guidance here.
Okay, you describe being charged with "Disorderly Conduct". What you were actually charged with isn't clear, as the entire Disorderly Conduct portion of the Criminal Code contains a number of offenses, and the only one that references specifically "disorderly conduct" is Section 175, typically the Cause Disturbance section, but that requires it to take place inside a building.
If they've charged you with Causing a Disturbance by impeding other persons, this is a very loose fit to the facts. I expect the most appropriate charge for the basic facts you have provided would be Mischief by interfering with the lawful use of property.
Regardless, you've been charged criminally, and if you missed court and had a bench warrant put out for you, I expect that you will have a failing to attend court charge, unless it was a bench warrant "with discretion" which means it only takes effect after the next court appearance if you don't show. If you weren't arrested by the police for not showing, and didn't get processed on another charge, this is what happened.
As for your question regarding being able to enter the US, there is no definitive answer to this. The US has some of the strictest criminal inadmissibility laws and policies, let alone the rest of their immigration rules. US Immigration and Border Services Officers have extremely broad powers.
Generally, the US rules for criminal inadmissibility are such that any person with a conviction for a crime involving Moral Turpitude is inadmissible. This covers a wide range of offenses and would include many obvious ones and some not so obvious. This is but one criteria.
Section 212 of the US Immigration and Naturalization Act deals with non-US persons wishing to enter the US.
The basic grounds for being denied entry are any person who;
A crime of moral turpitude would include such crimes as fraud, theft, housebreaking, kidnapping, robbery, murder, arson, forgery, rape or sexual assault. Certain other crimes are not crimes of moral turpitude, for instance, impaired driving.
This being so, where an offence involves some element of reckless conduct, such conduct may constitute a crime of moral turpitude. Therefore, the placing of pylons in the middle of the roadway could certainly be considered a reckless act and quite obviously could get you excluded on that ground alone.
Now there is a "Single Crime Exception" to this rule and it applies when the offence is punishable by a year or less and the sentence imposed does not exceed six months
There is also a Petty Offense Exception where the offense is one where;
a.) he or she committed only one crime
b.) the maximum penalty possible for the crime did not exceed imprisonment for one year; and
c.) the non citizen seeking admission was not sentenced to a term of imprisonment longer than 6 months.
Clearly, the only way to determine whether one meets the above elements of the exception requires an examination of both the conviction documents and the underlying law of the offense.
Now all of this being said, it deals with CONVICTIONS. And this is the issue that you have before you. You have not been convicted, and here we have a right to be presumed innocent until proven guilty. This does not necessarily hold true with Border Services and entry to the US, where entry is not a "right" and one can be be issued an instant 5 year ban at the border for pretty much anything that appears slightly deceptive, suspicious or troublesome. And there is no real review process (although on paper there is) and they rarely get overturned.
The problem that Border Services has, is they see the charges, and they will ask you the details, and it will likely be considered a CMT (Crime of Moral Turpitude) because of the recklessness involved. And if convicted this excludes you, and also, without a conviction, they don't know if your sentence length might also exclude you and so they would no doubt, as they typically do, err on the side of caution and turn you away.
The risk you run at the border, is the chance that they might issue a 5 year ban, which, besides the obvious repercussions, would also get you flagged on their system and you would expect to be held up even after the 5 years expired.
Border officers have access to CPIC (Canadian Police Information Center) and your pending charges would be visible. Most Border officers will refuse to admit persons who have pending charges, even in the absence of any previous conviction. This is standard practice and ultimately, the decision is completely in the hands of the Border officer who interviews you.
Generally, Canadians facing criminal charges are best to avoid attempting to enter the US altogether if they can until their charges are dealt with.
If the charges are withdrawn, an individual can go to the border and safely say they have never been convicted of a crime. They must acknowledge affirmatively if they are asked if they've ever been charged however. As even those whose charges were withdrawn were once charged. This oversight would be enough to get a 5 year ban.
And I have heard, although it's not in written policy, of instances where persons whose charges were withdrawn, being turned away because they had at some point in time, been charged with an offence even though they were never convicted.
If after court is done, a person is convicted and they want to travel to the US, they should commence the procedure for obtaining a US Travel Waiver, which is basically the providing of full disclosure and getting advance permission to enter.
A Canadian Immigration Lawyer can assist with this process, however it is not a necessity and it is something that an individual can do themselves and the entire US Travel Waiver application is available online.
I hope this helps to answer your question.
