OK, here is what I recall from when I was working as a recruiter.
If you have a conviction under the criminal code you will be unable to enrol in the CF for a certain amount of time. The amount of time that you have to wait depends on the sentence handed down to you. If I recall correctly, you can't join while on probation. However, for a firm answer, go to the recruiting centre, ask to see an MCC, and pose the question to them. They will know where to look it up in the Recruiter's Handbook.
Do NOT try and slip this one under the radar. It will be found, and you will face consequences.
Now, on to something that needs to be addressed; urgently.
Dlew: your use of the English language is beyond atrocious. You are applying to become an officer, and if you succeed you will need to be well spoken and to write well. The odd spelling mistake is not the end of the world. However, a complete disregard of punctuation, poor diction, and disorganized writing are something else completely.
As an officer you will be expected to lead troops. If you communicate with your troops the way you communicate here, your troops are going to think that you are either not too bright, or pretty bloody sloppy. Either way, it bodes badly for you.
A few specific points to consider:
I->The pronoun used to refer to yourself, is capitalized.
'->Goes into contractions. He's, not hes; it's, not its
Your->It belongs to you.
You're->You are (see contractions above).
There->The place something is.
Their->It belongs to them.
They're->They are (again, contractions).
Ya, yeah->Not words for proper, polite, professional writing. Try 'yes'.
