If what you really miss from “Heated Rivalry” is Hudson Williams’s Canadian accent, the new reality show “Canada Shore” might be for you. The series is a spinoff of “Jersey Shore,” this time taking place at a beach house — yes, Canada has beaches — in Kelowna, British Columbia, where 10 Canadians meet and spend a summer together. And, there will be a familiar face since Snooki (of the Jersey edition), will be dropping in. Begins streaming Thursday on Paramount+.
