The Crimea democratically voted voted to leave Ukraine.  I am not sure Canada has any sound rationale to support Ukrainian war efforts.  If the shoe was on the other foot, and Quebec voted to separate, would the rest of Canada be in the right to launch a war to take back the best parts of Quebec?  Would Quebec be in the wrong to seek military assistance from France to protect her interests?  

The whole thing seems fishy, and the Ukrainians aren't exactly models of freedom and democracy.  Ukraine often portrays itself as a misunderstood victim of oppression and starvation.  The country has a well documented history of corruption, and was a willing participant in atrocities against its own citizens and against neighboring countries  (azov battalion).   Canada should save some money and sit out this mess.  Let the people decide even if Canada doesn't like it.   There would be a lot more peace to gain by restoring relations with Russia than pouring money into Ukraine.
