I know little about Swan River. All I know is it is 6 hours away from Winnipeg. A full time RN position seems tempting, along with all the grants you can get from the Manitoba Gov't for relocating and with working in rural areas. But positions are also available in Winnipeg, you can start part time (and still get full time hours), gain seniority, then if a full time position opens up you'll have better chances of getting it.
Goodluck!
