Canadian Permanent Resident entering Canada with expired US passport

I’m a US citizen and a Canadian Permanent Resident. During my visit to my terminally ill mother in the US last year my passport expired. I just noticed it and am returning to my home in Canada the end of February. With the Covid epidemic going on it will take too long to renew my passport. I do have my valid Canadian permanent resident card and since my passport is expired and can’t fly I’m planning on crossing by Land. Will I have any problems entering Canada with my Canadian permanent resident card and expired US passport. I do have my birth certificate and my valid US drivers license to show that I am who I say am.
