Firstly, you're in the right thread. Welcome.
It's only been two months, so it might be a bit too early to set the alarms ringing. Perhaps he would usually be able to pay on time but due to unforseen circumstances, he was unable to do so. Perhaps he's going through a rough patch.
With regard to rent, bearing the above in mind, you can tolerate the delays for the time being. Give it a few more days time, then you better pay him a visit and address with him the issues of late payment of rental and unpaid utility bills, as the latter may accumulate and burgeon into one huge load on you later on. The way he reacts can tell whether he's gonna improve things or otherwise.
However, if you smell a rat and you want to cut him off while it's still early and forfeit the deposit, this is what you have to do:
1.Do you have a tenancy agreement?
2.There ought to be a clause stating that in the event the tenant fails to pay monthly rent by X date, the landlord can terminate the agreement. You may have to give one month's notice in advance.
3. Once he defaults after X date, send him a letter terminating the tenancy.
4. Forfeit the deposit as it is to cover the one month rent which is still outstanding as well as rent for the one month notice period - make sure that he settles the utilities, or else, use the money from the half-month deposit to clear the bills.
5. Once the 1 month period is up, tell him to vacate the premises.
What happens after that is hard to guess. On one end, he might be graceful and leave without kicking up a fuss. On the other end of the spectrum, he might damage your house and leave in a huff and without any trace.
I know of such tenant who filled up the landlord's toilets with faeces, clogged it with bottles, and then kept on flushing it until the whole toilet was flooded. The end result? I leave to your imagination ya.
So weigh your options carefully first before deciding.

Added on January 5, 2011, 2:18 pmIf you subsequently sue him for unpaid rental and you get a court order in your favour, you can send it to CTOS for them to enter into their database. Any judgments where there is a monetary sum involved would be welcomed by CTOS. If it is just to humiliate or embarass him just because he did not pay you rent now or if you evict him, CTOS is not the right avenue.
Eviction would be the last resort. Cross that bridge when you reach it.

Wow ...thanks man... it can be a hell
...let see how it goes..
