Ever notice how 2015 marked a turning point for Canada's economy? That's when the gap between Canadian and American economic performance started widening—measurably, consistently, and in ways that couldn't be ignored.

Before 2015? The two economies tracked pretty closely. Similar growth rates, comparable metrics, parallel trajectories. Then something shifted. The divergence became unmistakable across multiple indicators.

What triggered this split? Was it policy decisions, commodity price crashes, structural issues, or something else entirely? The data tells a story, but the why behind it remains a puzzle worth examining—especially for anyone tracking how macroeconomic shifts ripple through global markets.
