Ontario holiday destinations rivalling Hallmark movie sets can be found throughout the province, but few scenic locales rival the picturesque charm of the historic Unionville area of Markham, Ont. If you're planning a trip to Unionville, which proudly calls itself "the holiday town," Main Street is absolutely worth a stroll, with impressive holiday decorations lighting the way. For those seeking an Instagram-worthy photo op, the Unionville Holiday Chair lets you pose in front of a giant illuminated Christmas ornament. The town also hosts a Santa Claus Parade and a Breakfast with Santa event hosted at select Main Street restaurants. And to top off the experience, a Christmas market, horse-drawn carriages, and roaming carolers bring the town to life, making Unionville feel like a place straight out of a Christmas movie.
