Catching up in a Registered Retirement Financial savings Plan (RRSP) can really feel inconceivable. You have a look at the room you didn’t use, the years you didn’t make investments, and the market that in some way stored transferring with out you. However an RRSP doesn’t want a miracle inventory. It wants time, self-discipline, and companies that may hold compounding when you get again on monitor.
That’s why I’d have a look at WSP International (TSX:WSP) and Lumine Group (TSXV:LMN). One offers buyers publicity to infrastructure, power, transportation, and environmental consulting. The opposite presents a Constellation Software program-style path by means of area of interest software program companies. They’re very totally different firms, however collectively, they provide a catch-up RRSP each sturdiness and progress.

Governments and firms hold spending on the stuff that makes the financial system work. Roads, bridges, energy techniques, water networks, mines, clean-energy tasks, and knowledge centre infrastructure all want engineering and consulting assist. WSP sits proper in that stream.
The corporate has grown from a Canadian engineering title into a worldwide skilled companies agency. It earns cash by advising, designing, managing, and supporting giant tasks. Its newest quarter confirmed why the inventory nonetheless belongs on a long-term watch record. Within the first quarter of 2026, WSP’s adjusted earnings earlier than curiosity, taxes, depreciation, and amortization (EBITDA) rose 16.5% to $622.2 million, whereas backlog hit a document $19.7 billion. That backlog offers buyers a clearer view of future work, even when the financial system slows.
The TRC Corporations acquisition additionally provides a well timed catalyst. The deal strengthens WSP’s U.S. energy and power enterprise proper when electrical energy demand retains climbing from knowledge centres, grid upgrades, electrification, and industrial progress. That offers WSP one other lane for long-term enlargement.
The danger comes from valuation and execution as WSP doesn’t commerce like a hidden discount. Large acquisitions can even carry integration complications. If infrastructure spending slows or margins disappoint, the inventory might wobble. Nonetheless, for RRSP buyers attempting to catch up, WSP presents the form of regular progress profile that may do heavy lifting through the years.

Lumine Group brings the punchier facet of the portfolio. It trades on the TSXV, however don’t let that idiot you into pondering it’s tiny. Lumine owns and acquires software program firms targeted on communications and media. Its mannequin seems to be acquainted as a result of it got here from the Constellation Software program household.
For RRSP buyers, that mannequin will help as a result of nice software program companies can throw off recurring income, excessive margins, and money stream. Lumine buys firms it may possibly maintain for the long run, then works to enhance operations and profitability. It doesn’t want each enterprise to turn into a rocket ship, however a repeatable system that may hold working over a few years.
The newest quarter got here with a blended, however nonetheless helpful, message. Income rose 17% to US$208.3 million within the first quarter of 2026, helped by acquisitions. But working revenue slipped 3%, and free money stream obtainable to shareholders fell from final yr. So, this isn’t an ideal quarter to brag about at a cocktail party.
Nonetheless, that’s precisely why Lumine seems to be fascinating now. The market tends to punish slower natural progress and lumpy money stream. However an acquirer like Lumine can look uneven from quarter to quarter whereas nonetheless constructing long-term worth. The important thing catalyst stays capital deployment. If administration retains shopping for nicely, integrating nicely, and bettering margins, the compounding machine can hold working.

WSP and Lumine make sense for any Canadian attempting to catch up in an RRSP. WSP presents confirmed infrastructure progress inside a tax-sheltered account. Lumine presents software program compounding. Neither one ensures a easy journey, and but each give buyers one thing higher than a fast wager: companies with lengthy runways and actual causes to continue to grow over time, too.
