Father passed 4 days now & seems sister is possibly not sharing the million plus estate!

I have a question and sure maybe I'm wrong. My sister lives in Toronto and I live in Florida and she took care of my father a few months before he passed. My Father was able to shower and pretty much do most things himself, but sister beyond a nurse she would make sure he didn't fall and she helped with the feeding tube he used for the last 2 months of his life. My younger sister that is married and has no mortgage or bills has been kinda evasive regarding money in bank he has which should be substantial considering he was frugal and like my sister had no bills. She already said that everything is 50/50 as it's only the two of us. I was up in Canada 3 weeks before he passed as I wanted to see him, but I still have no idea what the will says, granted I do know she and my Dad made it so that everything isn't going in Probate. My sister pretty much did all this and I have no idea if I'm truly in the will. She also has made up her mind that the house will not be sold till the spring and hasn't asked me what I think, as she has started it was what my Dad wants and she has to honor that. So basically I have Zero input, my wife says my sister will probably screw me over. I have already said she's is a hardcore Christian and would never do this to me, but wife just laughs. Am I being paranoid or is this something that happens more than we truly know?

Thanks in advance for any thoughts you all may have over this issue I'm having!
