Grapevine Virus Testing

CCOVI’s Grapevine Virus Testing Services is now open to our clients. Our hours will be more limited, but we hope to do your essential tests.

To keep everybody safe, service procedures will be slightly different for accepting samples:

Step 1:
Download and fill out the Sample Submission form here (or at the bottom of this page)

Step 2:    
Email the form to as a PDF, scan, or picture of the filled form. (No paper forms please!)

Once we receive the order, we will schedule sample drop-off for the next day.

Step 3:
Package your samples in a closed box or bag with the company name on the outside.

Step 4:      
Bring your samples to Inniskillin Hall at the scheduled drop-off time. We will set up a table outside of the entry doors, since all of the doors are locked.  Leave your samples on the table and we will retrieve them shortly.

  • Sample drop-offs will be scheduled so that customers can avoid contact with each other. We will be setting up appointments between 8 a.m. and 5 p.m., Monday to Friday.
  • Make sure there is no headspace in your sample bottles so they can be stored overnight, if needed.

Thanks and talk to you soon!

The Grapevine Virus Testing Service drop-off is Inniskillin Hall 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, along the blue construction fencing. Drive forward toward the buildings. Inniskillin Hall is to the right, with purple-red accents on the windows.

There is one “Reserved CCOVI” parking spot in front of the building available for quick parking. Put on your four-way flashing lights, then walk toward the Shipping & Receiving dock. Turn right into the fire lane between the buildings. Ahead, there will be a tent covering a filing cabinet where your samples can be left for Analytical Services.
