Thank You.
yes my wife got approved for spousal open work permit.
As per best of my knowledge It is not recommended to apply together its better if she apply for study visa first lands in Canada and start her studies and then you can apply for sowp. It is also not recommended to apply for visitor visa if your wife is applying for study permit as chances for getting a sowp approved is high as compared to visitor visa.
It will be fine to show the same saving account its better if it a joint account.
