ClaimMechanism
The Productivity Mega Deduction would cut Canada's overall effective tax rate on new business investment from about 13% to 6.4% (US: 16.9%). It names mining property, pipelines and LNG, dropped the low-carbon condition for LNG, and applies to assets bought from September 15, 2026, though it is still a draft, not law. The tilt toward resources is clearest here, not in C-39.
