Bank has been frozen for 4 weeks because I sold BTC

I live in Canada and bank with Scotiabank. So I sold some BTC on localbitcoins.com, received payment through E-transfer. My bank flagged the transaction, disabled all my accounts and asked for proof of how I acquired the money. I gave them screenshots and an explanation of what occurred. It wasn't even a large sum of money either around 870$ CAD(647$ USD. They told me they consider Selling BTC for $ to be fraud because BTC isn't legal tender?? i asked if I would be charged with a crime and was told no. Haven't been given a time line on if or when I will get access to my accounts back or what will happen to the money I have in there. via /r/Bitcoin http://bit.ly/2WmVXnx
