What do you mean by saying "My partner"? Are they a true common-law partner, where you have lived together for at least 365 consecutive days?
At one time a person could work remotely from Canada, without needing a work permit, so long as they had no Canadian clients, nor were remunerated by someone in Canada.
That may or may not have changed, but worth exploring.
As mentioned, `living' in Canada as a visitor would be challenging; you'd need to have your own health insurance, for starters.
