How to invest while abroad without PFIC liability?

I am a U.S. citizen living in Canada. I have maxed out my RRSP here and want to invest in mutual funds or ETFs, but am concerned about triggering PFIC tax liability. I believe I can open a Canadian account here and invest in an ETF listed on the U.S. stock exchange and are set up as U.S. domestic entities with PFIC risk. 

 

Does anybody know if this is true? Or have any other investment strategies for my situation? 

 

Thanks in advance!
