Hello - Forgive me if I'm beating a dead horse, but can anyone provide some hard facts about the reality of attending a business function in Canada with a U.S. DUI? The stories online are sensational, but I have yet to find a 'real person' who has ever been denied entry.

I have pursued every angle and suggestion I can find, which is why I am here asking a question that has been asked a million times.

Facts of this case:

Arizona DUI from 2012. Sentence completed - I can provide documentation to that effect. I refused blood test (made Officer get warrant, which he later admitted lying in order to obtain). Don't know if that will show up as a separate 'encounter.' Complete one year suspension for refusal.

Only conviction in my 50 years. Note AZ requires jail time for all impaired driving convictions.

One other arrest in the early 1990's - someone punched me for no reason and the police arrested everyone in order to sort it out. All charges dismissed. I didn't even remember this until it was brought up during my 'booking' so I know it's in a system somewhere.

Travelling for meeting at our Vancouver office. Employer will provide supporting documentation. My manager is willing to travel on same flight for added support, if that will help.

Consulate website indicates that, with Foreign Service Strike, TRP could take a year.

I will attempt to obtain whatever documentation is required for a TRP application.

I've heard so many stories ranging from "I lied about conviction, they found it and still let me in" (another person with an AZ DUI from last year) to the horror stories featured on forums like this.

Can anyone shed any light based on actual current experience? I have a gut feeling that these denials are the exception, rather than the rule, based on the numbers - 10's of millions of visitors and less than 7000 getting turned back. I get stunned looks from friends and colleagues that travel constantly for business - they think I'm making this up. It seems that at least one of these people would know someone who got denied for some old infraction.

I guess my real questions are:
1) Can a Border Agent, seeing a record like mine on the computer, still let me in at his/her discretion?
2) What are the odds of getting a TRP at YVR if I provide the documentation listed above and have me $200 ready?

Thanks for taking the time to read and respond.
