Canada Tax Update

Week ending May 16, 2026
Priority: Federal + Ontario

Changes since last brief

The biggest development this week is Ontario’s introduction of legislation to implement expanded HST relief on new homes. Federally, Bill C‑31 continues through Parliament with additional details now publicly available regarding automatic filing and tax measures. No major new CRA administrative policy changes surfaced this week beyond ongoing implementation items.

Top 3 Changes

1) Federal — Bill C‑31 progressing through Parliament

Status: Proposed
Effective date: Pending Royal Assent / phased implementation

Bill C‑31, the Budget 2025 Implementation Act, No. 2, remains one of the most significant federal tax developments. Measures include automatic filing for lower‑income individuals, changes affecting trusts, crypto‑asset reporting frameworks, and immediate expensing proposals for certain manufacturing and processing buildings. Additional implementation detail became available this week through Finance Canada and LEGISinfo updates.

Who’s affected: Individuals receiving government benefits, tax preparers, trusts, crypto‑asset businesses, multinational groups, and corporations investing in eligible facilities.

Client recommendations:

• Review trust structures for anti‑avoidance implications.
• Crypto‑related businesses should begin preparing for enhanced reporting obligations.
• Eligible corporations considering capital projects may want to evaluate timing for immediate expensing opportunities.

2) Ontario — Legislation introduced for enhanced HST relief on new homes

Status: Proposed legislation
Effective date: Proposed temporary relief from April 1, 2026 to March 31, 2027

Ontario introduced legislation supporting implementation of expanded HST relief on eligible new homes. Buyers of qualifying homes valued at $1 million or less could receive full relief of up to $130,000 when combined with federal participation. Relief phases down for homes above $1.5 million.

This is a material update because Ontario has now moved beyond budget announcements into legislative implementation.

Who’s affected: Home buyers, builders, developers, investors, real estate lawyers, mortgage brokers, and residential landlords.

Client recommendations:

• Builders should review APS wording and rebate assignment clauses.
• Purchasers should confirm transitional rules before closing.
• Real estate professionals should avoid guaranteeing final rebate amounts until regulations are finalized.

3) Ontario/Federal — Combined HST rebate planning becoming significant for developers

Status: Proposed / implementation phase
Effective date: April 1, 2026 (proposed)

The expanded Ontario proposal, together with anticipated federal coordination, could materially alter pricing and cash‑flow planning for residential developments. Industry commentary now indicates combined relief could substantially affect pre‑construction affordability and project feasibility.

This has become increasingly important for assignment transactions, investor purchases, and GST/HST rebate structuring.

Who’s affected: Developers, construction companies, investors, tax advisors, and residential purchasers.

Client recommendations:

• Developers should revisit pricing models and marketing disclosures.
• Investors should assess GST/HST implications on assignments and rental structures.
• Accounting firms should monitor CRA guidance once legislation advances.

Itemized Changes

Federal — Automatic filing initiative expanding

Status: Proposed
Finance Canada confirmed expanded automatic filing initiatives intended to reach up to 5.5 million low‑income Canadians by the 2028 tax year. This could materially increase access to benefits and credits for non‑filers.

Recommendation: Advisors working with seniors and low‑income clients should prepare for increased CRA automation and verify CRA account information remains current.

Ontario — Enhanced housing rebate details clarified

Status: Proposed legislation
Ontario clarified that enhanced relief would apply across a broader range of qualifying purchasers and homes than existing rebate programs.

Recommendation: Builders and legal advisors should carefully track final eligibility wording and transitional provisions.

Deadlines (Next 60–90 Days)

• Ongoing: Monitor Bill C‑31 parliamentary progress and amendments.
• Upcoming: Ontario HST implementation legislation and related regulations expected to continue advancing through spring/summer 2026.
• April 1, 2026 – March 31, 2027 (proposed): Temporary enhanced Ontario housing rebate period.

Advisor’s Recommendations

• Review residential real estate transactions carefully for transitional HST treatment.
• Monitor Bill C‑31 closely before implementing planning strategies.
• Trusts, crypto businesses, and capital‑intensive corporations should begin proactive implementation reviews now.
• Developers and investors should revisit project assumptions given the proposed housing rebate expansion.
