Cool, thanks for sharing the info. Good luck with your travel!
I'm not sure if the financial documents would be any different in spousal case, but when I had applied for my parents TRV I attached the following documents:
Notice of assessment (NOA) - Previous year
T4 - Previous year
Bank statements - Last 4 months
Salary slips - Last 4 months
Apart from that my parents had also attached their proof of funds anyway, like balance certificate issued by bank, property valuation (to show ties to home etc.).
