Question re XAU/USD and USD/CAD

I am new to Forex so please excuse if I have butchered something.

Gold tanks today (I think based on stronger factory output report for November, and adjusted October numbers)

So why does the USD/CAD rise? CAD is commodity based.

Based on that alone I would expect USD/CAD to fall, giving a chance to go short and pick up an easy 20 pips.

Am I missing an oil report or something else that would have negated the Gold drop? Certainly it was not based on an announced cabinet shuffle.

Thoughts?

When gold / oil tanks it’s bad for CAD, hence the rise of USD back up towards parity. The pair you’re looking at is USD/CAD so good news for CAD means that USD/CAD falls and vice versa (all other things being equal).
