Not much to say, really.
AS a deemed resident yo ureport ALL income to Canada, and as Cdn gov't worker in US, you report ALL income to IRS except for your Gov't wages.
Merely splitting up your assets and not selling them, is not a taxable event in either country.
Since you will hardly be taxable in US, neither as married nor as singlew, it would probably be best to wait to trigger any investment income after you are single, as this income will fall below your standard deduction in US, while this year it would be added to the top of ex-hubby's income, so would incur tax.
There will always be some Cdn tax liability on any profits, so it doesn't matter which year you start taking income for Cdn purposes.
I always prefer to defer taking income unless needed.
