I got caught under section 334(b), theft under $5000, in ontario first time. Need to appear in court. I'm guilty and would never ever going to do this mistake. I would not like to get those under my record. What are things should I do. Can anyone guide me for this please, so that my carrier not get affected. And what are the consequences for this. Thanking You...

Ask for diversion or alternate measures. Usually granted for a first offense, it will mean restitution and community service after which your record will be expunged.

Of course you could have found that out by reading any of the several threads here on this subject.
