Race promoter Francois Dumontier insists everything is on track for next month's Canadian GP.
Earlier, there were reports that the Circuit Gilles Villeneuve's new pit building may not be ready.
But promoter Dumontier, who was in the Barcelona paddock at the weekend, said the new facilities will be unveiled by none other than F1 CEO Chase Carey on Wednesday.
"I'm not saying that Bernie Ecclestone would not have come," he told Le Journal de Montreal, "but when I asked Chase, he accepted immediately.
"It shows the importance of Montreal on the F1 calendar."
Dumontier says he feels sorry for his fellow promoters in Spain, who look set to see their Barcelona race dropped from the 2020 calendar.
"In the past I've had these turbulent moments, but I have no more such worries," he said.
"I can't wait to present our new facilities to the world of F1," Dumontier added.
"The garages have been redone from top to bottom and adapted to the times of the day. They are magnificent."
Chase Carey agreed: "The new facilities will solidify the foundations of the Canadian GP."
