Well Proto, you just may want to practice your best cheesy grin

and brush up on that Queen Elizabeth wave!!!
It appears that there are 2 celebrations happening in Osoyoos on July 1 - the Canada Day festivities, along with the Cherry Fiesta. Most of the activities are located at the Osoyoos Community Beach & Park... with a parade scheduled as well. The pancake breaky starts things off at 6AM and the events continue through to the fireworks that conclude at 11:30 PM.
If I recall, Highway 3, which goes through the centre of town, is also referred to Main Street and I have a feeling that's where the parade route will run. As long as you don't drive through between 10 AM and noon, you should be okay without additional decorations on your vehicle!
