GO Train service on Lakeshore West and the Barrie GO lines will be down this weekend due to planned construction.
It comes the same weekend as the first concert series of the year at Rogers Stadium featuring Bruno Mars and Doors Open Toronto.
Construction of the Lakeshore West line is a part of the GO Expansion with work continuing at Long Branch GO and on the Burloak Drive underpass.
Service will run between Niagara Falls and Aldershot. Buses will then travel between Aldershot and Bramalea GO where riders can then connect to Union using the Kitchener GO Line. The buses will stop at West Harbour, Aldershot Burlington, Oakville and Clarkson Go Stations.
There will be additional trains added to the Kitchener line to accommodate the increased ridership.
