Toronto will be pulling an all-nighter for Nuit Blanche this Saturday, and it looks like the weather — and the TTC — will be co-operating.

Here’s this weekend’s transit schedule, weather, and events:

Transit

The TTC is offering extended service for Lines 1, 2, and 3 through the early hours of Sunday morning. Subways will be running every 10 to 15 minutes on Lines 1, 2 and 3 from 1:30 a.m. on Sunday morning until normal service resumes at 8 a.m.

Streetcar service will also be extended overnight on the 509 Harbourfront and 511 Bathurst routes. Buses on the 300 Bloor-Danforth and 320 Yonge routes will run all night as well.

Line 4 Sheppard will operate on its usual schedule.

Nuit Blanche will trigger diversions on the 6 Bay, 121 Fort York-Esplanade and 501/301 Queen routes.

Four TTC routes — 5 Avenue Rd, 94 Wellesley, 506 Carlton, 300 Bloor-Danforth — will be diverting because of Sunday morning’s CIBC Run for the Cure.

The TTC is advising customers to monitor ttc.ca and follow @TTCnotices on Twitter to get real-time updates on these adjustments.

- Grand Magazine Street between Bruyers Mews and Fort York Boulevard

Weather

October’s teeter-tottering weather will continue this weekend, with a typical October day on Saturday — a nippy 5 degrees in the morning, warming to 13 in the afternoon, partly sunny throughout — followed by a muggy, wet day on Sunday.

Temperatures on Sunday will reach 21 degrees, and the rain will start early — likely sometime overnight on Saturday, or early Sunday.

In other words: if you plan on sleepwalking through Nuit Blanche ‘til the early hours of Sunday, bringing an umbrella or light jacket wouldn’t hurt.

Events

Nuit Blanche

Toronto’s annual art walk starts at sunset on Saturday. Most of the installations are sprinkled around Nathan Phillips Square, but there’s art featured nearly everywhere (check out the map here).

There’s a lot to see this year, which is why we asked Nuit Blanche artists what they were most looking forward to. The artists mentioned 16 installations in particular — read about them here.

Craftchella

Liberty Commons — a massive brew pub near King Street West and Dufferin Street — is hosting Craftchella on Saturday, a daylong Ontario craft beer festival. Ten dollars gets you a sampling glass and two drink tokens (additional beers are $2). Liberty Commons will also be selling burgers and ribs at the event.

Buffer Festival (Friday to Sunday)

Buffer is the “world’s largest digital-first film festival,” starting on Friday and finishing up on Sunday. Tickets are $25 for individual screenings — all of which are taking place at TIFF Bell Lightbox.
