Hi, year 2018 i couldnt get any tenant for my property. Can i still claim expenses such as mortgage interest, property tax, etc. thanks,

So long as you tried to rent out the property and can prove it, then you can claim these expenses. 

How do I enter my rental income and expenses in TurboTax?: https://turbotax.community.intuit.ca/replies/2647946
