**PATENT & PRODUCT CONTEXT:**
- Canadian Patent Number: [PATENT_NUMBER]
- Medicinal Ingredient/Product: [PRODUCT_DETAILS]

**YOUR TASK:**
Provide a comprehensive Canadian Patent Term Extension strategy addressing:

   - Assess eligibility for transitional provisions (pre-October 2017 approvals)
   - Evaluate alternative extension mechanisms (section 45/46 adjustments for regulatory delays)
   - Identify exclusion criteria (antibiotics, process patents, etc.)

2. **MAXIMUM TERM CALCULATION**
   - Calculate CSP duration (minus days between patent grant and NOC issuance)
   - Apply statutory caps (maximum 2 years for CSPs)
   - Calculate remaining patent term vs. CSP term overlap
   - Determine optimal filing windows (must file within 120 days of first NOC)

3. **REGULATORY COMPLIANCE ROADMAP**
   - Detail CIPO filing requirements for CSP applications
   - List required Health Canada correspondence documentation
   - Identify priority dates and critical deadlines
   - Outline declaration/evidence requirements for medicinal ingredient authorization

4. **STRATEGIC ANALYSIS**

   - Assess patent portfolio sequencing (linkage with pending divisionals/continuations)
   - Evaluate pediatric exclusivity implications (if applicable)
   - Identify potential third-party challenges or clearance issues

5. **DRAFT SUBMISSION ELEMENTS**
   - Template language for CSP application to CIPO
   - Key claim construction arguments for "medicinal ingredient"

- Account for [SPECIFIC_CONSTRAINTS] (e.g., pending litigation, Orange Book listings, prior CSPs on same patent)
- Address both human and veterinary medicinal products if relevant
- Consider biosimilar entry strategies and data exclusivity periods
- Note any COVID-19 or exceptional regulatory delays affecting timelines

**OUTPUT REQUIREMENTS:**
- Structure with clear legal citations (Patent Act sections, CSP Regulations)
- Include actionable checklists with calendar deadlines
- Flag high-risk compliance gaps requiring immediate attention
- Provide confidence levels (High/Medium/Low) for each eligibility determination
