Compliance Coverage

Every Saint Lawrence Seaway Filing — Validated Before Submission

The Saint Lawrence Seaway operates under dual Canadian/US authority, creating a uniquely complex multi-jurisdictional compliance requirement. SLSMC requires ECOS (Electronic Clearing System) pre-arrival notice 24 hours before lock entry — while CBSA and CBP impose separate border clearance requirements. CanalClear validates all filings across all three authorities before you touch any portal.

1

ECOS Pre-Arrival Notice

SLSMC requires 24-hour advance notification via ECOS. CanalClear validates vessel data, cargo manifest, and transit timing before submission to SLSMC.

2

SLSMC Vessel Registration

Vessel particulars, classification certificates, safety docs — formatted to SLSMC requirements. Automated dimension validation against Seaway-max constraints (225.5m LOA, 23.8m beam, 7.92m draft).

3

CBSA Pre-Arrival Notice

Canada Border Services Agency requires PARN (Pre-Arrival Review Notice) for all commercial vessels entering Canadian waters. CanalClear generates CBSA-compliant manifests.

4

CBP eNOA/D Filing

US Customs and Border Protection requires 96-hour advance eNOA/D for vessels arriving from international ports to US Great Lakes ports. CanalClear tracks US vs. Canadian port calls to trigger correct requirements.

5

Mandatory Pilotage

Foreign-flagged vessels require licensed Great Lakes or Seaway pilots. CanalClear flags pilotage requirement and generates required pilotage request documentation for GLSLPA.

6

NOAD — Notice of Arrival/Departure of Dangerous Cargo

Transport Canada NOAD filing for vessels carrying Annex I, II, or III MARPOL cargo. CanalClear validates cargo classification and generates NOAD with correct lead times.
