A heads up to anyone taking the subway this weekend: Trains won’t be running between Union and St. Andrew stations because of scheduled construction at the second platform at Union Station.

All trains on the University-Spadina line will terminate southbound at St. Andrew.

Trains on the Yonge line will terminate southbound at Union.

TTC riders can take the Carlton, Dundas, Queen or King streetcars to connect between lines.

Regular service resumes on Monday at 6 a.m.
