For Canadian restaurateurs that are experiencing rent-related issues with their landlords during Covid, the Canada Emergency Rent Subsidy program may be helpful.
Under CERS, the government may subsidize up to 90% of your rent. You must qualify, of course (and there are several ways to qualify), but signing up for this program is relatively easy - it's an online form that doesn't take very long. As long as you can show that you've had a covid-related drop in revenues, and have an eligible rent expense, then you're likely a fit for CERS.
You can also apply retroactively for months starting from October 2020. During the registration process, you set up direct-deposit to your bank account, and once you register and are approved, your subsidies take only 3-8 days to be paid to you.
So if you have a landlord that has been less than helpful during Covid, then it might be worth looking onto CERS.
