Quebec's political parties unanimously adopted a motion today condemning what they called the "authoritarianism'' of the Spanish government's actions in Catalonia.
Parti Quebecois Leader Jean-Francois Lisée tabled the motion that was accepted by all members of the National Assembly.
The motion also called for Spain and its restive Catalonia region to engage in dialogue and to resort to international mediation if both sides agree.
Premier Philippe Couillard, Lisée and CAQ leader Francois Legault, shook hands after the motion was presented.
Catalan separatists staged a referendum on Sunday despite Spain's insistence it was illegal.
Spanish police, following orders from a judge to prevent the referendum, clashed with voters and supporters Sunday, resulting in over 900 people receiving medical attention.
The Catalan government, which has many links with Quebec, plans to declare independence from Spain in the coming days.
Quebec and the Catalan government signed a co-operation agreement in 1996 that extends into many areas including culture and education.
The province also has a foreign bureau in Barcelona, which is the capital and largest city in Catalonia.
