No you cant show grocery bills unless it states both of your names and address.Thank you . Yes we have joint lease since from last 3 years and joint bank AC from the last 2 years. can we show groceries bill etc. as well?
You can send a copy of both of your driving licenses showing your name and address. A copy of both your T4s showing the same address, any other tax documents...etc. Any bills with both of your names and address should also be good.
Just make sure you make your case as strong as you can when it comes to proving your co-habitancy.
