Fargo to Winnipeg

I’m flying to Vancouver out of Winnipeg and back at the end of May and I’m trying to figure out a way to get there either from Fargo or even Grand Forks. Flights are much cheaper out of The Peg and I don’t want to have to pay for my car to sit in a parking lot for a week. Are there any options at all? I tried searching for a rental car for each travel day and it didn’t give me any options.
