Divorce grounds are federal and identical everywhere, but the forms, filing fees, and property rules are provincial, so the province you file in changes the practical experience.
Ontario runs divorces through the Superior Court of Justice using Form 8A for a joint or uncontested divorce and Form 8 for a contested one. Property division for married spouses follows the Family Law Act equalization of net family property model, which is distinct from how unmarried partners are treated. Where parenting claims are made, the court expects a Form 35.1 affidavit on decision-making responsibility and parenting time, sworn before a commissioner. Financial disclosure is required whenever support or property is in issue, and a Canadian affidavit or statutory declaration template is often needed alongside the main application.
British Columbia processes divorces through the Supreme Court, with property division under the provincial Family Law Act on a presumptive equal-division basis that, unusually, also captures many unmarried spouses who meet the cohabitation threshold. The one-year residency and one-year separation rules apply as everywhere, and BC permits same-roof separation where the spouses prove they ended the relationship.
Alberta applies the Family Property Act to married spouses and, in many situations, to adult interdependent partners, which broadens who is caught by the property regime compared with some provinces. Applications proceed through the Court of King's Bench.
Quebec sits inside the federal Divorce Act for the divorce itself but applies its own civil-law system to property through the family patrimony rules, and the forms and terminology differ from the common-law provinces. The province processes the large majority of its files as joint applications.
Across all provinces, the married-versus-common-law distinction reshapes the property analysis entirely, so the document you sign must match your actual legal status.
