Prime Minister Justin Trudeau is announcing significant rent relief for businesses that can't afford to pay their landlords at a time when their operations are shut down due to the COVID-19 pandemic.

The federal help, expected to lower rent by 75 percent for affected small businesses, will be provided in partnership with the provinces and territories, which have jurisdiction over rents.

The Canada Emergency Commercial Rent Assistance for small businesses will provide forgivable loans to qualifying commercial property owners to cover 50 percent of three monthly rent payments payable by eligible small business tenants experiencing financial hardship during April, May and June.

The loans will be forgiven if the mortgaged property owner agrees to reduce the eligible small business tenants' rent by at least 75 per cent for the three corresponding months under a rent forgiveness agreement, which will include a pledge not to evict the tenant while the agreement is in place.

The small business tenant would cover the remainder, up to 25 per cent of the rent.

Affected small business tenants are those paying less than $50,000 per month in rent and who have temporarily ceased operations, or have experienced at least a 70 percent drop in pre COVID-19 revenues.
