Canadian dollar trading will be thin on Monday
Monday is a holiday in most of Canada
USD/CAD has been steadily sinking towards 1.3500 today with the pair last down 85 pips to 1.3518.
Monday is a high-risk for the pair because you have virtually all major markets open but Canada shut down. So if there's a big move due to oil or risk aversion, you might see gappy or choppy moves (or a market that's asleep at the switch).
For retail traders, I believe there's an opportunity there but it's a risk as well.
