What
@21Goose is saying is correct, but I just want to point out that if your choose to apply as Common Law partners (not legally married), not only do you have to live together for a year, you have to have proof and documentation that you've been residing together for a year. This can be in the form of a lease or house purchase with BOTH your names on it , joint utility accounts (e.g., electricity, gas, telephone, internet), joint credit card accounts, joint bank accounts, vehicle insurance papers showing both partners as living at the same address, or copies of government-issued documents showing that both people reside at the same address. Cell phone bills, pay stubs, tax forms, bank or credit card statements, insurance policies, etc., which show that you live at the same address, are acceptable. So make sure you have at least one of those, and if you don't, sign up for something as soon as you're up here, to get the countdown clock started ASAP.
Hope this helps!
