Over the last few days, the CECRA website has been updated to provide more information on the extension through to September. it notes:
For the July, August and September extensions:
Those who qualified for CECRA for small businesses based on existing program parameters will automatically be eligible for the additional 1, 2 or 3 months without reassessing whether they continue to have a 70% revenue decline in July and August. Participation in the 1 or 2-month extension is voluntary. Both existing applicants to CECRA for small businesses and new applicants will be able to apply for the July, August and September rent reduction.
If the tenant has committed to entering into a new lease to continue to operate its business at a new location, the tenant must provide the program administrator with a copy of the signed lease. The tenant may be eligible for the CECRA for small businesses on an exceptional basis.
For more details, please refer to CECRA for small business terms and conditions (in PDF) and the FAQs.
