Commuters can expect trickier travel during what promises to be a wintry feel to the first spring weekend of 2014 with up to 5cm of snow expected by Saturday morning.

The TTC says there will be no subway service this weekend between Bloor-Yonge and St. Andrew station on the Yonge-University-Spadina line due to continuing signal upgrades. Close to 50 shuttle buses will run on Yonge St., between Rosedale and King stations before heading over to St. Andrew station.

However, the closure of Union station means commuters will not be able to walk from the subway station to the main union station. Those looking to head to the Air Canada Centre will have to walk from King or St. Andrew stations, or take the 6 Bay bus. The stretch between Bloor-Yonge and St. Andrew will reopen Monday morning.

There are no major road closures set for this weekend. Sunday should be clear but with colder temperatures and a high of just -6C, according to Environment Canada.
