Thanks for your feedback.Is it mandatory to show the 1year income statement in canada?Does it means I won't be able to sponsor my wife before getting job? Also,I have to wait for 1year after getting the job.
I don't have specific experience for this so take what I say with a pinch of salt (which you should in general for anything on internet).
You are eligible to sponsor a person on day 1 of becoming pr and staying in Canada. But realistically it depends on below factors.
For sponsorships, cic is interested in making sure you have enough funds to comfortably live your life for a period of time (3 years for spouse) in Canada. If you can show enough liquid assets in your balance either in your home country or Canada, show a stable job history, then those will make a convincing case for sponsorship. On the other hand if you are unemployed or availing government support or unable to financially handle life incidents like job loss or divorce, then those would be red flags.
