A lot of you are talking about filing taxes and if you should let Revenue Canada know about your marriage or not.
My opinion on this issue:
Do it as soon as possible. Add your foreign spouse on your tax return. They will ask you to state your spouses total income for 2011 in Canadian dollars and submit a copy of your marriage certificate. So you should send a copy of translation of your Nikkah nama and a copy of your original Nikkah nama. Its better if you have transferred some money to your spouse in Pakistan. This way you can prove that your spouse is dependent on you.
Huge Benefit:
If you include your spouse in your tax return, you will get a lot more return if your spouse isn't working abroad or working but has very little income in CAD. Talk to your accountant and work out the scenarios. Last year I included my spouse in my tax return and I got back a big chunk of the Fed & Provincial tax portion back.
Thank me later
