After months of souring relations with the West, Russia has launched its attack on Ukraine, commencing a full-scale military invasion of its neighbour.
Tensions between Moscow and the West over Ukraine date back to 2014, when Russia annexed the Crimean Peninsula. But these tensions reached new heights in late 2021, when Russia began to mobilize over 100,000 troops along the Ukrainian border.
Western intelligence agencies had warned that these troop movements were a prelude to an invasion. In preparation for this, the U.S., Canada and other allies had responded by deploying their own troops to NATO allies in Eastern Europe and sending military aid to Kyiv.
Attempts at diplomacy were unsuccessful. The Kremlin has called on the West to discontinue the further eastward expansion of NATO while the U.S. has urged Moscow to respect Ukraine's sovereignty. After Russian troops stormed into Ukraine, Canada and other Western nations responded by strengthening economic sanctions on Russia.
Here is a timeline of some of the key moments leading up to the invasion:
