Hello, i am in Canada on a work permit valid till 2025 (working in a company) and i have a valid visa (same date). I applied for express entry and received my COPR last month. I m still waiting for my PR card. I am planning to visit my home country after 1 month, in case i dont receive my PR card from now till then, can i travel and come back to Canada using my visa/work permit? Or they are already canceled after receiving the COPR? Will i need travel documents from my country?
