A pop-up vaccine clinic at Toronto's Downsview Arena is offering Pfizer vaccine doses to anyone 18 years of age or older who lives or works in a select group of hot-spot postal codes.

The clinic, located at 1633 Wilson Ave., is now offering vaccine appointments on a first-come, first-serve basis until supplies run out.

The clinic is serving postal codes that begin with M3J, M3K, M3M, M3N, M6M, M9L, M9M, and M9N — eligible residents will need to bring a piece of ID that proves where they live or work in order to get a dose.

If you're eligible and want to get your dose, you may want to get down there quickly. One Twitter user waiting for their turn wrote at 9:13 a.m. that the line is "literally weaving around the block."

On Tuesday, the province lowered the age requirement for vaccine appointments in hot-spot zones around the province, allowing anyone 45 years of age or older to sign up for their dose at a mass immunization clinic.
