Thank you, Jason. Good morning, everyone and thank you for joining us to discuss our second quarter 2021 results. We believe that throughout the second quarter, the company has continued to build on the momentum we have seen so far in 2021 and we feel well positioned heading into the second half of the year and beyond as we continue to grow and diversify our modular building rental businesses and scale our B2B travel technology ecosystem. A key highlight in the quarter is consolidated rental revenue of $23.3 million, which is a 61% increase over the comparative quarter. This is our core and most profitable revenue stream. Contributing to this robust growth was another record quarter for rental revenue in our MSS division and a strong recovery in WFS stemming from a number of larger cap rental projects coming on stream. The company also showed continued progress in scaling the LodgeLink platform, with significant progress in penetration of the U.S. market, where LodgeLink grew gross revenue 650% versus a comparative quarter. In the MSS segment, rental revenue grew to $14.6 million or by 60% from the comparative quarter, a sixth consecutive quarterly record.
Our outlook for MSS is positive as utilization remains very high, rental rates are increasing and organic fleet additions are expanding rental capacity. Bidding activity and backlog for MSS sales, which we view as a recurring revenue stream, remains strong throughout our diversified end markets, with particular strength in British Columbia, Ontario and the Eastern U.S. regions.
As most of those listening are likely aware, we closed on the acquisition of Vanguard in – Vanguard Modular in November of 2020. Since then, Vanguard’s operating performance has been strong and is trending ahead of our initial expectations as we are seeing a very active education market in Eastern and Southeastern U.S. Integration has continued and synergies announced at the time of the deal approximately $500,000 per year are on track to be realized as we exit 2021.
Our WFS business unit is showing further signs of recovery and benefiting from our efforts to diversify by end-market and geography. WFS rental revenue of $8.6 million grew 62% from the comparative quarter as utilization has recovered to pre-pandemic levels on the back of previously announced contracts in Australia and Canada, which are in support of infrastructure and mining-related projects.
As a result of these contracts, we expect continued improvement into the second half for WFS utilization and rental revenue.
As announced in October of 2020, the Mi’kmaq of Nova Scotia, Black Diamond Limited partnership received a letter of award to provide the Goldboro LNG project, with a turnkey accommodation solution for up to 5,000 workers.
We are aware that the Goldboro LNG project is being re evaluated, but remain well-positioned to meet any accommodation needs pertaining to the project as it undergoes further review. Larger pipeline camps for each TMX and Coastal GasLink are now fully on rental stream and showing increased occupancy, which we expect will continue. We remain optimistic on the continued growth of the LodgeLink platform, a digital marketplace offering that is bringing innovation to the crew travel industry. LodgeLink’s total room bookings grew 400% to 43,300 from Q2 2020.
While gross revenue grew 500% from the comparative quarter, U.S. gross revenue as mentioned was up 650% year-over-year and helped offset expected lower booking volumes from certain Canadian resource sectors or our sector customers within the quarter. At the end of the second quarter, LodgeLink had approximately 5,300 listed properties, representing roughly 500,000 rooms, servicing 580 distinct corporate customers.
Assuming pandemic-related travel restrictions continue to ease in the U.S. and Canada, we believe the platform is poised for ongoing growth as we continue to scale. We believe the positive quarterly and year-to-date financial performance of the company is a result of our strategies over the last several years to diversify our rental stream by customer, by industry and by geography. The company generated over $14 million of operating cash flow in the quarter. And based on our customer makeup and contracts in place, we believe the stability of this cash flow is as strong as ever, which should inform long-term value creation as we compound our returns and expand our fleets.
We expect the balance of the year will show strengthening results as we progress on our strategic objectives, growing and diversifying our businesses. I will now turn the call over to Toby for some further details on the first quarter financial results. Toby?
