The Global Affairs office spoke, in a statement on its website, a day after lawyer Miguna Miguna was deported.
Canada asked the Jubilee administration to uphold the Constitution.
The statement came in the wake of events which followed Nasa leader Raila Odinga's unofficial oath on January 30.

"The Kenyan government should allow freedom of expression and respect court orders, including those that order the release of those granted bail," the statement read.
Canada further questioned the unlawful detention of opposition members without due process or access to counsel, and the shutdown of certain media outlets.
"In the words of the Chief Justice of Kenya's Supreme Court, "there have been worrying developments in the administration of justice that threaten the rule of law". A free media and adherence to the rule of law are essential components of democracy."
Canada said Kenyans of all political beliefs should come together to peacefully resolve their differences.
