Vanguard VCN or TDB900? Exchange rate risk Difference? HELP!

[Goldielocks]

Hi!

I am trying to decide between investing in Vanguard VCN with its 0.27 MER, or TDB900 with its 0.33 MER.
I am investing in CDN $, and already have sufficient exposure to US$ currency fluctuations with other holdings.

But - Is there a difference between the two in terms of CDN to US$ currency risk? 
There must be but I am having a blank moment figuring out exactly what that is.

Can someone explain for me?

(BTW, I already own some of both of these funds, but VCN is already in the account I am buying in, and except for potential currency risk, I would buy that one.)

VCN is an all-Canada ETF with 0.06 MER. You must mean a different fund?

My Bad,  I read the wrong line, you are right.  It shows an actual management fee of 0.05%, and a MER of 0.11%. Ticker:  TSX:VCN Canada

Interesting how similar, yet different they are.
