Air Transat (TS, Montréal Trudeau) restarted operations on July 23 offering both domestic and transatlantic flights. The carrier announced in a press release that it operated six flights on the first day of operations after a "112-day shutdown", from Montréal Trudeau to Toulouse Blagnac, Paris CDG, and Toronto Pearson as well as from Toronto Pearson to London Gatwick, Montréal Trudeau, and Vancouver Int'l.

Many European countries have reopened to Canadians during the past couple of weeks after the European Union listed Canada as one of 14 countries from which travellers have again been recommended unrestricted entry. Every European Union and Schengen zone member state still makes its own decisions regarding entry restrictions. As such, Air Transat's capacity is predominantly deployed to Europe with flights currently being offered out of Montreal and Toronto to France, Greece, Italy, Portugal, and the UK. It has also resumed flights to the Dominican Republic, Haiti, and Mexico.

In its press release, Transat said its leisure carrier would primarily use its fleet of six A321-200NX(LR)s on its transatlantic network this summer. According to ch-aviation analysis of Flightradar24 ADS-B data, it has so far reactivated two A321-200s, one A330-200, and one A330-300.
