ETA validity

[Gabzila]

hello, I was multiple times in Canada for 6months , because my boyfriend is living there (I am from Czech Republic) .my eTa is valid till March 2020. When do I have to apply for another eTa registration, when I am going there this June 2019 till December ? Is it ok to go there with this eTa expiration date? Or do I have to apply for another eTa ?when I will come back to czech still before it will expire ? Possibly when I come back to Canada in 2020, and will apply for new one, do I have to wait till it expire or can I apply let’s say a month before it expires?
Thank you for your answer

If your eTA is still valid, you do not need to apply for a new one. If you will be travelling very close in time to when your eTA expires, then apply for a new one a few weeks before.
