Canada warmed up for the Gold Cup with an impressive 4-2 friendly win over Canada in Toronto on Saturday, while Mexico went down to Switzerland by the same scoreline.

The start of Canada's Gold Cup camp was overshadowed by three of the Vancouver Whitecaps' internationals falling ill in the aftermath of their CONCACAF Champions Cup final defeat to Club America. 

That prompted Jesse Marsch to claim the Whitecaps camp had been targeted by a "poisoning", but his players showed no ill effects against Ukraine.

Canada's record goalscorer, Jonathan David, struck twice inside the first 24 minutes, tapping home following a goalmouth scramble then sending a glancing header into the top-left corner from Tajon Buchanan's corner.

Promise David added a third 31 minutes into his Canada debut, dispossessing Ukraine's Valerii Bondar then finishing coolly under Anatolii Trubin.

Buchanan flicked home nine minutes from time as Canada continued to put their opponents to the sword, though Illia Zabarnyi and Oleksandr Zinchenko made the scoreline more respectable with late goals for Ukraine.

One of Canada's foremost rivals at the Gold Cup, Mexico, were on the wrong end of another six-goal thriller, against Switzerland in Salt Lake City.

Switzerland fielded a strong team and went ahead when Breel Embolo rounded Raul Rangel to tap into an empty net after 20 minutes, the only goal of the first half.

Early in the second period, AC Milan's Santiago Gimenez equalised with a scrappy header, but substitute Zeki Amdouni soon swept home to restore Switzerland's lead.

Bologna's Coppa Italia hero Dan Ndoye extended the visitors' lead, and though Angel Sepulveda fired inside the near post to make it 3-2, Fabian Rieder completed the scoring in the 90th minute.

Canada open their Gold Cup campaign against Honduras in Vancouver on June 17, three days after Mexico face the Dominican Republic in the opening match of the tournament.

Data Debrief: Gimenez ends long wait in defeat

Gimenez's goal was his first for Mexico since he hit the winner in the 2023 Gold Cup final against Panama, ending a run of 13 international appearances without scoring.

Mexico could have few complains about their defeat, with Switzerland recording more shots (15 to 10) and expected goals (1.81 to 1.13 xG) than El Tri.

Canada's clash with Ukraine was even more enthralling, with Marsch's team generating chances worth 2.47 xG to their visitors' 2.21.

David's brace took him to 34 in 62 appearances for his country. The striker, who has multiple suitors after leaving Lille as a free agent, averages 0.55 goals per game for Canada.
