The Pink Slayer strain is a specific Indica-dominant hybrid cannabis strain that appears to be available primarily through certain dispensaries or delivery services, particularly in the Toronto area. It is not a widely documented, well-known strain with a universally recognized genetic lineage in major cannabis databases. 
Based on available retail information, here are some reported characteristics of the "Pink Slayer" strain:
Type: Indica
Availability: It has been offered by specific delivery services like Cafe Delivery in North York and Scarborough, ON.
General Profile: The name suggests a combination of genetics from "Pink" strains (like the popular Pink Kush) and "Slayer" strains (such as Hippy Slayer or Demon Slayer).
Effects and Aroma: Specific details are limited, but "Pink" strains are often known for sweet, vanilla, or candy-like aromas and potent, relaxing, body-focused effects, while "Slayer" strains often have pungent, diesel, spice, or earthy profiles with heavy effects. The combination likely offers a unique blend of these traits.
