Employment Insurance regular benefits
www.canada.ca
I received EI benefits in the past. Do I need to submit a new application?
If you started a new EI claim within the last 52 weeks and there are still weeks payable on that claim, we will automatically reactivate (renew) your existing claim.
However, in some cases, it may be to your advantage to cancel or end your old claim earlier and start a new claim, because this may increase the amount of your benefits or the length of your benefit period.
You must decide whether or not to cancel or renew a claim based on your own personal situation.
It is important to consider:
If your claim is reactivated and you work after the start of that claim, you may be able to establish a new claim when your existing claim runs out.
In order to establish a new claim you must have enough insurable hours and meet the qualifying conditions for a new claim.
If a new claim is established instead of reactivating your existing claim, the remaining weeks payable on the existing claim will be lost.
Additionally, a one-week unpaid waiting period must be served on a new claim before you are entitled to receive payment

EI Regular Benefits
www.canada.ca
Outside of Canada while on EI
You are not usually eligible to receive regular benefits while you are away from Canada. However, you may receive regular benefits if you show that you are available for work in Canada while abroad. You must also notify Service Canada of your travel by filling out a travel form on My Service Canada Account (MSCA) or through your bi-weekly report.
You can be outside Canada for a period of seven consecutive days for the purpose of:
attending the funeral of a member of your immediate family or a close relative
accompanying a member of your immediate family to a medical facility, provided that the treatment sought is not readily available in the family member's area of residence in Canada
visiting a member of your immediate family who is seriously ill or injured
attending a bona fide job interview
You can be away from Canada for a period of 14 consecutive days for the purpose of conducting a bona fide job search.
If you indicate that you have taken measures to be reached if an employment opportunity presents itself during your absence and that you are able to return to Canada within 48 hours, we will accept that you have proven your availability.
One measure we take to enforce this rule is to compare EI information with information from the Canada Border Services Agency. If we find you have been out of the country while collecting benefits, we will determine whether you were entitled to receive those benefits. If you were not entitled to receive them, we will calculate how much we overpaid you, and you will then have to repay the benefits.
We may also impose penalties of up to three times your weekly benefit rate or three times the amount of your overpayment. As well, you may have to work more hours or, in the case of fishing benefits, you may need more insurable earnings to qualify for benefits in the future.
