He will definitely get a fair trial but the process is very slow. Frauds are in some cases very difficult to prosecute unless there is a strong paper trail as well as corroborating witnesses.
It really depends on the type of fraud involved. If it was some sort of local Ponzi scheme or investment/real estate scam (the sort of stuff you see on "American Greed"), it could be fairly challenging, as there's usually quite a few people who are complicit. However, what likely happens is those folks get pinched and roll over whoever's fled. If Rick is the Last Man Standing (and thus unable to turn state's witness and cop a plea bargain), it could be very tough for him.
The second major type is "wire fraud," which is a pretty broad category. Basically it means you used some sort of electronic means (emails, bank wires, whatever) to commit the crime. If that's the case, then whoever investigates that in Canada (the Secret Service does it here in the US) will likely have boxes of incriminating evidence. That's VERY hard to defend against, and the best you can frequently do is to, once again, throw your accomplices under the bus before they do it to you, and cop a deal.
A tough position to be in. Didn't know the guy, but never heard a bad thing about him.
