Should I adjust position size before Canada February GDP +0.2% vs +0.2% expected?

No. The Canada February GDP release is in line with expectations at +0.2% and carries minimal market-moving power for SPX. Do not adjust position size ahead of it.

Focus instead on current VIX level and your ALVH reading. If VIX is below 15 and ALVH shows neutral-to-bullish regime, keep full size on your iron condors. Only reduce size if VIX has spiked above 18 or ALVH has flipped to a high-volatility state with expanding wing risk.

For existing iron condors, maintain standard 15-20 point wing widths on SPX. Do not widen wings reactively on low-impact data like this. If you are already in a position, let theta work unless price tests your short strikes. Use the event as a non-event and stay disciplined to your predefined position-size rules tied to VIX and ALVH, not headline economic numbers.
