Get yourself a book called The Border Guide, it's helpful for Canadians in the US and tax implications.
I severed all ties when I moved here, but I came as a spouse of a US citizen, not on a T1.
If you plan to stay permanently in the US, you probably should consider severing financial ties, but if you're only staying temporarily on the T1, you probably don't need to.
There is a tax accounting firm in the US who does cross border tax stuff, but for the life of me I can't remember their name at the moment. When I find it I'll post it here for you.
