49th Parallel Wealth Management — Expert guidance for cross-border financial planning
49° 00′ N · Cross-border wealth, planning & tax

Expert guidance for cross-border financial planning.

For individuals and families whose lives, income, and assets cross between Canada and the United States.

Most advisors are licensed on one side of the border and guess at the other. We coordinate investments, planning, and tax across both — so nothing falls into the gap between two systems.

The challenge

The complexity most advisors can't handle.

Living across the border multiplies every financial decision. These are the places one-country advice quietly costs cross-border families money.

Two systems, no bridge

Two tax systems, zero coordination

The CRA and the IRS both want their share. Without one advisor watching both, you pay twice or miss treaty relief you were owed.

Works north, breaks south

Investments that break at the border

A portfolio built in one country can trigger punitive tax and reporting in the other — often without anyone warning you first.

Half the picture

An advisor licensed on one side

Your current advisor may be excellent — in a single jurisdiction. The other half of your financial life is left to guesswork.

Currency & income risk

Retirement income, two currencies

RRSPs, IRAs, pensions, CPP and Social Security must be drawn in the right order, in the right currency, taxed in the right country.

Who we serve

Do you recognize your situation?

If your money, your family, or your future spans the 49th parallel, generic advice leaves money — and peace of mind — on the table.

01

Cross-border professionals

Dual citizens, green-card holders, and those relocating between the two countries who need both tax systems handled together.

02

Business owners

Entrepreneurs with operations, income, or buyers on both sides, planning toward a sale or succession.

03

Retirees & pre-retirees

Households coordinating RRSPs, IRAs, pensions, CPP and Social Security for tax-efficient retirement income.

04

Families & estates

Multi-generational families managing inheritance, gifting, and estate plans that must satisfy two sets of rules at once.

Investment philosophy

A few principles we don't bend.

A coherent philosophy applied consistently — so you always know the thinking behind your plan, on either side of the line.

Goals before markets

Portfolios are built around your life and timeline first — not around whatever the market is doing this quarter.

Long-term discipline

We don't chase noise. Costs, taxes, and behavior do more long-run damage than market dips, so we manage those.

Tax efficiency, both sides

Every holding is chosen with PFIC, treaty, and reporting rules in mind, so the after-tax result is what actually matters.

Coordinated & holistic

Investments, planning, and tax move together. One plan, one advisor, no hand-offs that drop the ball.

Transparency

Clear fees, clear reasoning, clear reporting. You should never wonder what you're paying or why you own something.

Active partnership

Your plan is reviewed as your life — and the rules in both countries — change. It's a relationship, not a set-and-forget.

How we work together

A clear path, start to finish.

No mystery, no pressure. You always know what happens next and what's expected of you — which is usually very little.

1
No cost

Discovery call

A short conversation to understand your situation and confirm we're the right fit for each other.

Analysis

Deep-dive review

We map your full cross-border picture — accounts, income, tax, goals — and find what's exposed or inefficient.

Strategy & implementation

A coordinated plan across investments, planning, and tax — then we put it in motion and handle the moving parts.

4
Ongoing

Partnership & management

Active management and regular reviews as markets, your life, and the rules on both sides keep changing.

What we do

Four disciplines, one coordinated plan.

Most households juggle an advisor, a planner, and an accountant who never speak to one another. We bring the conversation into one room.

Investment management

Discretionary portfolios built for your goals, risk, and cross-border tax reality — held in accounts appropriate to where you live and file.

Discretionary & advisory

Financial planning

A living plan covering retirement, cash flow, education, and goals — reviewed as your life and the rules on both sides change.

Goals-based & ongoing

Cross-border tax preparation

Coordinated Canadian and U.S. returns and planning, so treaty benefits are claimed, double taxation is avoided, and April holds no surprises.

Treaty-aware filing

Private consultations

Focused, paid sessions on a single question — a move, a sale, an inheritance — when you need senior cross-border judgment without a full engagement.

By the hour
The 49th parallel

Two countries. One financial life.

The border is a line on a map. Your money doesn't see it — but the IRS and the CRA certainly do. We sit in the space most advisors avoid.

  • RRSP, TFSA, RESP, IRA, 401(k) and Roth accounts treated as one coherent picture, not two competing ones.
  • Currency, residency, and treaty questions answered before they become expensive mistakes.
  • Investments selected with PFIC, foreign-trust, and reporting rules already in mind.
  • One relationship that follows you whichever side of the line you settle on.

Giving that earns relief on the side where it counts most.

The 183-day test

Will the U.S. count you as a tax resident?

Snowbirds get caught by a day-count most people have never heard of. Enter your days in the U.S. and see where you land against the IRS Substantial Presence Test.

Closer-connection (Form 8840) or the Canada–U.S. treaty may still change this — let's check.

Simplified estimate — not tax or legal advice. The Substantial Presence Test counts all U.S. days this year, one-third of last year's, and one-sixth of the year before; you may be treated as a U.S. tax resident if that total reaches 183 and you were present at least 31 days this year. This tool ignores exempt individuals, excluded days (certain medical, transit, and commuter days), the Closer Connection Exception, and treaty tie-breaker rules — any of which can change the outcome.

The cross-border wealth authority

Built for the space between two countries.

49th Parallel Wealth Management exists for one reason: most people living across the Canada–U.S. border are served by advisors who only understand one side of it. The result is missed treaty benefits, accidental double taxation, and portfolios that quietly create problems in the country no one was watching.

Lucas began his career in 2014 and went on to serve as a Director of Finance before relocating to Toronto in 2019 as a management consultant — building first-hand expertise across both countries’ systems while working with some of the most respected firms in the cross-border space. Having personally navigated a move across the border, he left the large-firm world to build something different: a fee-only, fiduciary practice where he could coordinate both sides of a client’s financial life and make a real difference. He holds the CFA and CFP® designations in both Canada and the U.S., and is the author of Crossing the 49th Parallel.

"People who live between two countries deserve advice that sees the whole picture — not half of it."

Frequently asked

Cross-border questions, answered plainly.

General answers to the questions we hear most. Yours will have details only a conversation can surface.

Can I keep my RRSP if I move to the United States?
Generally, yes. You can usually keep an RRSP after moving to the U.S., and the Canada–U.S. tax treaty allows the growth to keep deferring U.S. tax while it stays inside the plan — but only if it's reported correctly to the IRS. The details (and the reporting) matter, which is exactly the kind of thing we coordinate so a move doesn't create a tax problem you didn't see coming.
Do I need separate advisors for Canada and the U.S.?
That's the usual setup — and the usual source of trouble. When a Canadian advisor and a U.S. advisor each manage half your life without talking, decisions that look smart on one side can backfire on the other. The whole point of working with us is one coordinated relationship that sees both at once.
Can I reduce both CRA and IRS taxes at the same time?
Often, yes — through foreign tax credits, treaty provisions, and the order and location of where income and withdrawals happen. The goal isn't to dodge either authority; it's to make sure you're not taxed twice on the same dollar and that you're claiming the relief the treaty already entitles you to.
What is a PFIC, and why does it matter?
A PFIC — Passive Foreign Investment Company — is how the IRS classifies many ordinary Canadian mutual funds and ETFs when a U.S. person owns them. The tax treatment and reporting can be punitive and surprisingly expensive. It's one of the clearest examples of an investment that's perfectly normal in one country and a problem in the other, which is why we build portfolios with these rules in mind from the start.
How does my status affect me as a snowbird?
Spending winters in the U.S. can quietly pull you into U.S. tax residency through the "substantial presence" day-count test, even if you never intended it. There are ways to track your days and use treaty tie-breaker rules to stay on the right side of the line — but it takes planning before the trips, not after.
