Until September 24, 2022, you only need to have accumulated 420 hours of insurable employment during your qualifying period to qualify for EI benefits and receive a minimum of 14 weeks of benefits. This temporary rule will be replace by the existing rule after September 24th, 2022.

If you were assessed a violation, you may need more insurable hours to qualify for benefits. The required amount rises based on the number and seriousness of misrepresentations that have been recorded in the 5-year period before the start of your claim.

The qualifying period is the shorter of:

• the 52-week period immediately before the start date of your claim. or
• the period from the start of a previous benefit period to the start of your new benefit period, if you applied for benefits earlier and your application was approved in the last 52 weeks

Exception: In some cases, the qualifying period may be extended to a maximum of 104 weeks if you weren’t employed in insurable employment or if you weren’t receiving EI benefits.
