IRS and CCRA
 

I am a US citizen working in Canada as a permanent resident.
Could anybody share his/her experience filling income taxes to both CCRA and IRS? Any recommendation as far as Chartered Accountants who can assist in Ottawa?
I just don't want to be handcuffed and shackled the next time I visit my folks in the states.:D for failing to file income tax to IRS.
Thank You
