Holding two eTAs at the same time

[Evi1hamst3r]

I am awaiting my work permit, and would like to travel to Canada soon, with or without its approval.
In order to travel I need to obtain an eTA because I am living in Australia.
If my work permit is approved before I leave, and I have acquired an eTA, I will possess two eTAs one from my work permit and one I acquired manually.

Is this an issue? Can I hold two eTAs at the same time?

Thanks in advance!

unlikely as ETA is tied to your passport so any new one would replace the old one with a new start end date.
