One has source=NRCan-CanVec-7.0, the other source=CanVec 6.0 - NRCan
Is there a good reason for this redundancy?
If not, what is the best way to remove these duplicates?
I can think of different ways:
1) keep only the eldest entry
2) keep only the youngest entry
3) keep the older and add a note that the data is confirmed by NRCan-CanVec-7.0 
 
This is a case where someone imported CanVec improperly without resolving conflicts with existing data.

If both interpolation ways are the same, it doesn't matter which is deleted. You could investigate the changeset the more recent one came from and see if the entire thing needs reverting.

If they differ, look to see if one has been edited and keep that one. If neither have been edited, I'd presume CanVec 7 to be more accurate than CanVec 6 in absence of any other information.
