So I just bought a low mileage is 250 Awd drive a month ago, everything was fine until the last couple of days. I try to start the car yesterday and it won't start, just hear the starter clicking over. So I get it jump started and go to work
when I try to go home no start again, another jump start.
This morning I go to work and it starts but with some hestation, I go to work,
and try starting it 7 hrs later, no problem, two hours later no start again.
Is this a bad battery? or what could be draining the battery?

 

I am driving a 2006 IS350 here in Ontario .... colder winters than you .... no battery issue yet. After 4 years in a cold climate it is not unusual for a battery to show its age .... if it has been run flat 2 or more times then you are on borrowed time at 4+ years. These vehicles don't have a history of starter or alternator problems.

Put a volt meter on you're battery .... you should see 12v at rest, and 13-14v when running with a good alternator. The battery would have to be tested under load to see if its OK or not .... even a crap battery will read 12v if its not under load.

You will still likely have some warranty left so why not head to the dealer?
