According to Rick Westhead at tsn it's been going on for years:

Staff and contractors connected to the men’s national team have also filmed the closed training sessions of competitors, one of the sources told TSN, adding that Canada used a drone to record a U.S. training session before a Nov. 15, 2019, game in Florida. The U.S. won that game 4-1.
Two years later, Honduras stopped a training session in Toronto during World Cup qualifiers after someone spotted a drone overhead.
“I’d imagine there’s probably a lot of people in Canada that fly drones, I’m sure,” then-Canada coach John Herdman said at the time. “And when a big team like Honduras turn up I’m sure people are probably interested in what they’re doing when they come into our country. So I know for sure we won’t be heading into people’s countries too early because with drones these days, people can obviously capture footage. You’ve got to be really careful. So yeah, you got to be careful in CONCACAF. It’s a tricky place.”
Some staff and contractors were told the filming was part of their jobs and that they could lose their positions with the federation if they did not go along with the demands, one of the sources said in a series of interviews with TSN on Wednesday and Thursday.
