Palmer helps Sid and Cat as they navigate their way around the Ottawa River and its long and important history. They learn all about how Ottawa became such a hub that the Queen named it the capital of Canada and that the river had a lot to do with it. Sid and Cat visit the Canadian Museum of Civilization and learn about how the river system was the lifeblood of the area's Algonquin people and became a key in the first settlers establishing communities along the river's shores. Next, Parks Canada specialist Juan Sanchez shows Sid and Cat the ins and outs of the Rideau Canal and its system of locks and how it helped win the War of 1812. Valerie Blazeski goes underwater to show Sid and Cat what lives in the infamous canal's waters, then Jonathon Moore digs even deeper into the historical relics that are preserved in the canal's muddy floor. Get to the bottom of Ottawa's waterways on this episode of CG Kids!
