Last summer, Gordo, an Eastern Massasauga rattlesnake, met his demise on Matchett Road, but his genetic legacy lives on. A local reptile conservation expert confirmed that before his death, Gordo successfully mated, leading to the birth of seven baby rattlesnakes that are now being nurtured for future release in the area.
Jonathan Choquette, a PhD biologist heading the Ojibway Prairie Reptile Recovery program of Wildlife Preservation Canada, expressed enthusiasm for the development, highlighting the significance of preserving the Ojibway genetics within the offspring.
The Eastern Massasauga rattlesnakes, once abundant in Windsor-Essex, are now on the brink of extinction in the region, with estimated local populations dwindling to possibly fewer than 10 individuals. This species is the sole venomous snake in Ontario and is classified as critically endangered throughout the province.
Gordo, a prominent male Eastern Massasauga rattlesnake, was a key figure in efforts to bolster the population at the Ojibway Prairie Complex. Despite being raised at Toronto Zoo, Gordo’s lineage can be traced back to Eastern Massasauga rattlesnakes rescued in LaSalle over two decades ago.
Tragically, Gordo was found deceased on Matchett Road in September 2025, likely as a result of being struck by a vehicle. Identification was possible due to his implanted electronic transmitter. Choquette emphasized the urgent need for conservation efforts to ensure the survival of the local population.
Prior to Gordo’s passing, he had successfully bred with a female named Ashley. Confirmation of Ashley’s pregnancy came earlier this year when she underwent an X-ray at Toronto Zoo to replace her transmitter implant, revealing the presence of eggs.
The offspring of Gordo and Ashley, born through ovoviviparous reproduction, will be kept in captivity until they reach a year in age. The plan is for them to be released into the Ojibway Prairie Complex next summer, carrying forward Gordo’s legacy in Windsor-Essex.
Choquette emphasized the significance of this unique tallgrass prairie population of Massasauga rattlesnakes in Canada, underscoring its importance in preserving the country’s natural heritage.
