Adopting a puppy from USA to Canada?

Hi - Does anyone know if it'd be possible right now to bring a rescue puppy from the US to Canada? I foster for a small organization in the US and we have an adopter interested in Canada. We'd have health certificate for dog, and all vaccinations current, just not sure what other border restrictions there would be. Would I be allowed to enter Canada to deliver the dog? Or if we met at the border, could a Canadian come through and back again?
