Grapevine Virus Testing

COVID-19 Update

As of Monday March 16, Brock University has mandated that all non-essential employees must now transition to working off-site until further notice.

This means that CCOVI’s Grapevine Virus Testing Service will not be able to receive or analyze samples. We’re disappointed that we won’t be able to keep working with you through this tough time, but we take your health and safety very seriously. This decision was made to mitigate risk, encourage social distancing and protect the health and wellbeing of our clients, Brock faculty, staff, and students, and the broader community. We look forward to seeing you as soon as we can.

The Grapevine Virus Testing Service drop off is at the Analytical Services lab in Inniskillin Hall, room 215, at Brock University (1812 Sir Isaac Brock Way). View Brock’s interactive campus map or click on the map below for directions.


Navigate to Brock University’s northeast entrance, off Glenridge Avenue across from John Macdonell Street.  Turn west into campus.  There will be a small traffic circle.  Take the second exit from the traffic circle, which is marked with a short brown sign indicating “Shipping/Receiving”.  Drive forward toward the buildings.  Inniskillin Hall is to the right, with purple-red accents on the windows.

There are two “Reserved for CCOVI” parking spots in front of the building available for quick parking.  Put on your four-way flashing lights and follow the sidewalk to the entrance at the right.  Once in the lobby, turn left and follow the hallway to a set of purple double doors.  Turn right and IH215 Analytical Services is the first door on the right and they will be collecting the Grapevine Virus Testing samples.

*There are extra forms and further instructions outside of the lab if the door is closed.
