Used by topics

001Who would approve pipelines, mines, major projects, and environmental assessments — and would approvals actually get faster?Current sources show separate federal and Alberta baselines for impact assessment, environmental assessment, and energy regulation; independence would require explicit rules for project approvals, enforcement, consultation, equivalency, and recognition by other governments and markets.

Referenced claims

001environmental-assessment-pipeline-approvalsThe Supreme Court of Canada's 2023 Impact Assessment Act reference supports a narrower conclusion: federal assessment power has constitutional limits, but it does not eliminate every federal role over major projects.

002environmental-assessment-pipeline-approvalsThe strongest anti-independence / pro-federation caution is that faster Alberta paperwork would not by itself resolve Indigenous consultation, federal or successor environmental protections, interprovincial or international pipeline recognition, courts, financing, or market/export constraints.

003environmental-assessment-pipeline-approvalsClaims that independence would make approvals faster need project-specific proof showing which statutory steps are removed, merged, time-limited, or replaced and whether new cross-border, consultation, court, or market delays are avoided.
