There have been tons of times that courts have cited the Charter of Rights and Freedoms. A bit older, but in the early 2000s when courts started legalizing same-sex marriage province-by-province their decisions were often based off of the Equality Clause.
Worth noting of course that unlike in the US our constitution doesn't provide absolute freedoms. A good example of this is the role of free speech - in Canada we have restrictions on how you can spend money in elections to support a political party, whereas in the US their constitution protects speech absolutely, which makes it impossible to restrict the role of money in elections. And of course our constitution has the notwithstanding clause which just lets legislatures temporarily bypass some parts of the constitution, which is what Quebec does to keep its language laws.
