Tax Question re: Rental Condo

I have a question regarding taxes on a Rental Condo I own. I have been renting it out since December 2012, I generally do my own taxes so when I did my taxes for 2012 I just claimed the last month of Income and deducted the obvious things (mortgage Interest, Condo Fees, Property Tax).

Now that I have a full year of ownership/income from it I'm wondering if I should go see an accountant to do this or if I should just continue doing it myself. Basically If I do it myself I just claim all the Rent as Income and make the obvious deductions (mortgage interest, Condo Fees, Property Tax, and money spent on improvements) which will likely leading to me paying taxes on a few thousand dollars but after doing some reading I have heard you can claim depreciation on the building as well as a few other things. My question is to anyone who is either in a similar situation or has done taxes for someone in a simlar situation.

Is it worth claiming depreciation on the building? I will likely seek the help of an accountant if the answer is yes since a lot of the stuff involving CCA is confusing to me.
If not am I missing out on any other tax deductions? I own both of my cars so there is no leasing or financing.

Also any other advice would be greatly appreciated.
