Why has a president of the United States never met with the president of Canada?

امریکہ کے صدر کی کینیڈا کے صدر سے ملاقات کیوں نہیں ہوئی؟

They have no diplomatic relations

Canada has a prime minister, not a president

Due to no common interest

They have prolong conflict

Canada has a prime minister, not a president so a president of the United States never met with the president of Canada.
