Why was this new country Canada formed (3 problems)?

Canada was formed in 1867 primarily to address several key issues: First, there was a need for economic stability and growth, as the provinces sought to improve trade and access to resources. Second, political deadlock within the provinces, particularly in the United Province of Canada, hindered effective governance and prompted calls for a stronger, unified government. Third, concerns over security and defense against potential threats, particularly from the United States, motivated the provinces to unite in order to better protect their interests and maintain peace.
