Glacier national park (the Canadian one) Banff/jasper Icefields parkway
All are spectacular, all are close to each other, and can be enjoyed from the vehicle/a short walk if thats your thing.
Depending on when you plan to travel, some roads/parking areas may be closed. They start to open in April, generally.
Five days is probably fine, especially if you aren't into hiking and just plan on driving.
