The final spring tune-up for the Jays will take place on Monday, March 25th, but it won't be on Sportsnet TV or radio. But there's still a way you can watch it for free. MLB.com is showing the game vs. Pittsburgh gratis through its website, along with several other final contests.
You do need to sign up (which means you'll be bombarded with come-ons to buy a package from them in your email - although you can unsubscribe) but there's no charge or credit card needed to watch the game.

Are you sure about this? Sportsnet's schedule for Monday lists Jays and Pirates at 1:00 p.m. It should be a Pittsburgh broadcast (like last night), since it's a spring road game, but it appears it will air on Sportsnet.

I checked the Sportsnet press release on the schedule and it wasn't listed. Perhaps they've added it on a subsequent one. Either way, if you don't get Sportsnet or are out of your home when it airs, you can watch it online for free.
