Green Lantern haters rejoice, looks like Vipère won't be opening in 2021
They only posted the message in french on their Facebook page, but it says (roughly, translation by me):
La Ronde delays Vipère's opening date, the first free-fly coaster in Canada, which was planned for 2021.
Because of COVID impacts, the construction of the ride was delayed. Taking into account the current situation, the ride will open at a future date.
