Here are some ways that cohabitation can be proven in Canada:
Joint Lease or Property Ownership: If you and your partner have joint ownership of a property or a joint lease agreement, this can be used as evidence of cohabitation.
Joint Bills: If you and your partner share bills, such as utility bills or rent payments, these can be used as evidence of cohabitation.
Joint Bank Accounts: If you and your partner have joint bank accounts or credit cards, this can be used as evidence of cohabitation.
Witness Statements: Statements from friends or family members who can attest to your living situation can also be used as evidence of cohabitation.
Affidavits: An affidavit is a written statement made under oath, which can be used as evidence in court. You and your partner can each provide an affidavit stating that you live together as a couple.
