Samsung Gear S2 smartwatches also have a Nano SIM card slot. You'd have to activate a separate Public Mobile SIM card (with its own account, number, and Plan) for the smartwatch. You could use a Public Mobile SIM card on any number of unlocked devices, and (re)use the "triple punch" plastic spacers to downsize or upsize the SIM card form factor each time as needed, but Public Mobile doesn't support multiple simultaneously-active devices on one SIM card.
My understanding is that no Canadian carriers support eSIMs except in eSIM-equipped devices which are purchased (with contracts) directly from them. The much-hyped "reprogrammable convenience" features of eSIMs are not being (and likely never will be) embraced by Canadian carriers, they're deliberately sticking with single-use single-activation factory-programmed versions which guarantee sales and subscriptions.
