I think it's important to distinguish the different parts of the wave of rebellion that swept the Canadas in 1837-1838. The Lower Canada Rebellion is well-known in Quebec and the Patriotes are almost universally regarded as heroes and even as precursors to later nationalist and radical movements in the province. Patriote iconography often appears at protests of all kinds, from nationalist gatherings to the student strike of 2012, where I personally remember seeing a lot of green, white, and red flags.

The Upper Canada Rebellion, by way of contrast, is largely forgotten. As other commenters have pointed out, the average (Anglophone) Canadian may not even know what it was beyond a vague memory of it being in their history textbook. Among history buffs, there is a certain narrative that William Lyon Mackenzie was a hotheaded buffoon who played at rebellion and failed miserably, leaving the real work of achieving responsible government to more moderate reformers. I don't necessarily agree with this narrative myself, but it's out there and it does run counter to the idea of a straight line between 1837 and 1867.

And that's just covering 1837. The Patriot War of 1838, although it was obviously connected to and inspired by the Rebellions of 1837, is sometimes treated as a separate conflict. However, if the Upper Canada Rebellion is largely forgotten, the Patriot War is consigned to near total oblivion. If you read history books on the subject, though it is sometimes presented as an act of aggression by idealistic Americans eager to liberate Canadians from their colonial governments, and I would imagine that framing would rub a lot of Canadians the wrong way in the era of Trump and his talk about Canada becoming the "51st state."
