Does Germany now allow tri-citizenship?

Hi all,

I have been a duel British-German citizen since birth. 10 years ago I moved to Canada and am now looking to apply for citizenship here. I want to keep roots in both Britain and Germany (have family, friends, and interest in living in both in the future).

My question is - with the new Modernization of Nationality Legislation (StARModG) - is acquiring a third citizenship through naturalization possible? Or, would this disqualify me from maintaining my German citizenship?
