Can you please provide a reference showing eligibility to work remotely in Canada if the company does not do business with Canadian customers, because I can not find such a reference?You won't have a problem in Canada working remotely unless your company does business with Canadian customers. In that case you are not legally allowed to do it.
Meanwhile, I did find the following on an official Govt of Canada site, where the following question is asked...
"I am sponsoring my spouse or partner who is in Canada. Can they work while their application is being processed?"
Here's the response...
"Yes, but only if they have a work permit.
If you’re sponsoring your spouse, they can apply for an open work permit.
It will take us about 4 to 5 months to process the open work permit application.
Remember that while your spouse or partner’s permanent residence application is being processed, they must
- maintain legal status as a visitor, student or worker in Canada, and
- wait for their work permit application to be approved before starting to work"
No mention of "not doing business with Canadian customers".

Here's a related link "Bridging open work permit for permanent residence applicants". This one speaks to PR application using Express Entry, but the response is the same - need to apply for a valid work permit.
