"Get your skates on" is mainly a British saying, which basically means "hurry up".
The mink was bouncing back and forth between open water & the ice covered creek. The ice shelf allowed for some quick photo shots, before it was back to business (i.e. fishing) for the mink and disappearing into the grassy shore.
With much colder temperatures, it definitely is a matter of "hurry up", mink, before the entire creek freezes over & it's a return to the cold waters of the Bow River for fishing expeditions.
