Something you might want to think about.I really hope so. I'm tired of filing for Canadian visas and going through this ordeal so many times. Takes forever to scan all that crap (I swear to God my mum did not change since the last gazillion applications)
Last time they gave me just a few months. The particular expiry date matches other stuff in my docs (not passport) and heavily suggests a terrible inefficiency in their system (cant share details yet, unfortunately).
They clearly didnt spend any money on the contracted engineers who built it.
As you were issued a short validity TRV, the visa officer likely believed:
1. You don't have reasons to visit Canada multiple-times until your passport expiry, or
2. You were allowed to visit for just the specific, one-time purpose that you had stated in your application, or
3. You did not demonstrate that your ties to the US are far more stronger than those to Canada
If you believe you haven't submitted adequate documents/evidence for #3 then you can email/send a web form asap
