Ontario is a hotbed for paranormal activity. Several remnants of its dark history remain today, and they are popular locations for exploration by both paranormal researchers and thrill seekers alike.
Perhaps one of the most allegedly haunted places in the province is the Merritton Tunnel, or the Blue Ghost Tunnel. It is an abandoned railway that once connected St. Catharines to the town of Thorold. Built in 1876, the tunnel was constructed by a team of hundreds of men, who excavated the area using picks and shovels. During its construction, a total of 107 workers experienced fatal accidents; many of which were caused by falling rocks within the tunnel.
The tunnel remained operational for many years until one unfortunate morning when two trains collided with each other; head-on at full speed. While a few people survived the crash, several others were killed, which lead to the abandonment and closure of the tunnel.
Since then, many visitors have claimed to experience paranormal events within the passageway. Many swear to seeing the characteristic light blue mist of which the tunnel was nicknamed after. Echoes of crying children and "pushing" sensations near the mouth of the tunnel were noted, and some individuals even felt physically sick or nauseous during their visit.
Although the tunnel may sealed off, several people still make the trip to visit the tunnel anyway and enter through a separate opening. Though, explorers should take caution as there is no word as to how sound the construction of the tunnel is today.
