Are the salaries set in bitcoin? Or Canadian Dollars and then exchanged for bitcoin on payday at market rates? Either way, It seems I'd rather be paid in dollars for the stability then have the ability to trade these for bitcoin with dips in the market. Unless my salary is set in bitcoin and I'm counting on Bitcoin inflation to outpace dollar inflation.
