That most blessed of occasions takes place this week and next when a host of Toronto bars extend last call until 4 a.m. The impetus is Toronto Men's and Women's Fashion Week, which run back to back starting March 7th, but the you don't have to be a sartorialist to drink all night long.

The window for extended last call stretches from March 3 to the 15, but not every bar is authorized to serve until 4 a.m. each night during this period. The dates tend to be clustered around this weekend and next, so do make sure to confirm before planning your debauchery.

These are the bars with extended 4am last call in Toronto this week and next.

• Bloke & 4th (March 3, 4, 5, 10, 11 and 12)
• Brassaii (March 3, 4 and 8)
• Early Mercy (March 3, 4, 9 and 10)
• EFS (March 2, 3, 4, 8, 9, 10, 11 and 15)
• The Everleigh (March 3, 4, 7, 8, 9, 10, 11 and 14)
• Maison Mercer (March 4, 10 and 11)
• Same Nightclub (March 3, 4 and 10)
• Thompson Toronto (March 2, 3, 4, 5, 9, 10, 11 and 12)
• Wildflower (March 2, 3, 4, 5, 9, 10, 11 and 12)
• Wayward (March 3, 4, 10 and 11)

Note: As always, this list reflects establishments that are licenced to sell booze until 4am. They don't have to exercise that right, so call ahead to confirm, particularly early in the week.
