The 270 acre farm, in the family since 1933, will be cleaved by a rail detour line that will bypass downtown Lac-M ©gantic and cut a swath through some farms. On July 6, 2013, 73 rail cars from the Montreal, Maine & Atlantic Railway left a parked area nearby and sped down to the Quebec town and exploded, killing 47 residents and levelling much of the downtown area.
