There are two options for people to jointly hold title in a property in Canada, Joint Tenants OR Tenants in Common.
With Joint Tenancy, you and anyone else on the title will hold 100% of the interest in the property jointly, you cannot specify any percentages of interest. In addition, so-called Right of Survivorship applies to you by default. Should any of the title holders pass away, their share will automatically be absorbed by the surviving title holders.
With Tenancy in Common, there is no Right of Survivorship applicable to the title holders. If any one of the owners passes away, their share of the property will go to their next of kin in accordance with their will. In addition, you can specify the percentage of interest held in the property for each party on the title.
