Investors & landlords

I really appreciate you responding to my messages and thanks for your time. Here is my other question

I have a Canadian property which had a Building value of 200k USD bought in 2011 which was 202k CDN in 2011 because of CAD dollar being stronger in 2011. I am trying to file form 3115 to catch up on missed deprecations.  Since than Canadian dollar has been falling every year.   Please note the value in the CDN dollars remains the same but USD keeps changing because of exchange rate as can be seen in this table. 

 

Could  I convert the cost basis in USD based upon yearly average exchange rate each year and then deprecate it that way each year or do I need to stick to 2011 exchange rate and use that 2011 converted cost basis every year to depreciate
