The U.S.-Canada border is set to close at 11:59 tonight.  If the closure lasts into the late spring and early summer--the timeline some are predicting for when the many effects of COVID-19 may subside--it could prevent many Buffalonians from spending time at their summer cottages in southern Ontario.  As a result, summer rentals to Canadian residents, through AirBnB, property management companies, or otherwise, may increase.  At a time when the economy is not at its best, renting may help families as a second form of income.  Owners looking to rent out their cottage for a week, a month, or the summer should have a properly drafted rental agreement to (1) protect themselves from liability as best they can and (2) make sure their cottage is kept in the best possible condition at a time when they may not be able to check on it.
