The invasion of Seattle by Canadian baseball fans cheering on the Toronto Blue Jays is an annual tradition.

But this year's series against the Seattle Mariners at T-Mobile Park, taking place May 9-11, may look different.

There are still a ton of tickets available on Ticketmaster for the final of the three-game series between the Blue Jays and Mariners on Sunday, May 11. Plenty of the seats are available for $40, while some in the lower bowl can be snagged for as low as $73.

Both Friday and Saturday's games have plenty of seats that remain up for grabs as well. Friday's game has prices for as low as $39, while the lowest price available for Saturday's outing is $41.

What could also be playing a part in this is the active tariff trade war between the U.S. and Canada. One Reddit user confirmed on a Blue Jays forum that they won’t be attending due to the hostile situation between the two countries.

"My group of 60 have all cancelled," the individual wrote. "You guys do you, but we'll be here in Canada where freedom still lives, watching at home."

The recent tariffs put in place by U.S. President Donald Trump has had many Canadians boycotting all travel south of the border. There are plenty who say they will not be travelling down to spend their hard-earned dollars in the U.S. until the trade war comes to an end.

The series also takes place in May, whereas in past years it's been during the summer months. That could rule out many families from areas such as Alberta and Saskatchewan, whose children will still be in school.

Of course, the discrepancy between the U.S. and Canadian dollar could also be playing a big part in those north of the border choosing not to attend this year.

Right now, the Canadian dollar is just $0.70 American, makes tickets, travel, accommodations, and everything else that comes with a trip down to Seattle all the more expensive than years past.

Another part of the issue is that the Blue Jays aren't expected to field a very competitive roster this season. They missed out on several top-tier free agents who would have helped them get back into the playoffs, and has a result have several holes in their lineup entering the 2025 season.
