Item 7.01  Regulation FD Disclosure.

      During our earnings conference call on April 24, 2007, we highlighted the
      following outlook for the second quarter 2007.

      (Dollar amounts are approximations)

      For the second quarter of the year, we estimate our revenue to be
      approximately $235 million to $237 million. Price and volume growth is
      estimated to be 8% to 8.5%. Equity-based compensation costs are estimated
      to be $1.4 million. Depreciation and amortization expense is estimated to
      be approximately 8.8% of revenue and operating income before depreciation
      and amortization expense to be approximately $72 million to $73 million.
      We expect net interest expense to be approximately $8.3 million. Minority
      interests and other expense are estimated to be a combined 1.8% of
      revenues. We expect our effective tax rate to be 38.5% and our fully
      diluted share count to be approximately 70.9 million shares.

      These estimates exclude the impact of any additional acquisitions or any
      stock option or share repurchase activity that may be completed during the
      second quarter.

      Operating income before depreciation and amortization is considered a
      non-GAAP financial measure, and is provided supplementally because it is
      widely used by investors as a valuation and liquidity measure in the solid
      waste industry. It is not a substitute for, and should be used in
      conjunction with, GAAP financial measures. Management uses operating
      income before depreciation and amortization as a principal measure to
      evaluate and monitor the ongoing financial performance of our operations.
      Other companies may calculate this measure differently.

      Safe Harbor for Forward-Looking Statements

      Certain statements contained in this report are forward-looking in nature.
      These statements can be identified by the use of forward-looking
      terminology such as "believes," "expects," "may," "will," "should,"
      "anticipates," or the negative thereof or comparable terminology, or by
      discussions of strategy. Waste Connections' business and operations are
      subject to a variety of risks and uncertainties and, consequently, actual
      results may differ materially from those projected by any forward-looking
      statements. Factors that could cause actual results to differ from those
      projected include, but are not limited to, the following: (1) Waste
      Connections may be unable to compete effectively with larger and better
      capitalized companies and governmental service providers; (2) increases in
      the price of fuel may adversely affect Waste Connections' business and
      reduce its operating margins; (3) increases in labor and disposal and
      related transportation costs could impact Waste Connections' financial
      results; (4) increases in insurance costs and the amount that Waste
      Connections self-insures for various risks could reduce its operating
      margins and reported earnings; (5) Waste Connections' financial results
      are based upon estimates and assumptions that may differ from actual
      results; (6) efforts by labor unions could divert management attention and
      adversely affect operating results; (7) Waste Connections may lose
      contracts through competitive bidding, early termination or governmental
      action; (8) Waste Connections' results are vulnerable to economic
      conditions and seasonal factors affecting the regions in which it
      operates; (9) Waste Connections may be subject in the normal course of
      business to judicial and administrative proceedings that could interrupt
      its operations, require expensive remediation and create negative
      publicity; (10) competition for acquisition candidates, consolidation
      within the waste industry and economic and market conditions may limit
      Waste Connections' ability to grow through acquisitions; (11) Waste
      Connections' growth and future financial performance depend significantly
      on its ability to integrate acquired businesses into its organization and
      operations; (12) Waste Connections' acquisitions may not be successful,
      resulting in changes in strategy, operating losses or a loss on sale of
      the business acquired; (13) because Waste Connections depends on railroads
      for its intermodal operations, its operating results and financial
      condition are likely to be adversely affected by any reduction or
      deterioration in rail service; (14) Waste Connections' intermodal business
      could be adversely affected by steamship lines diverting business to ports
      other than those Waste Connections services, or by heightened security
      measures or actual or threatened terrorist attacks; (15) Waste Connections
      depends significantly on the services of the members of its senior and
      district management team, and the departure of any of those persons could
      cause its operating results to suffer; (16) Waste Connections'
      decentralized decision-making structure could allow local managers to make
      decisions that adversely affect Waste Connections' operating results; (17)
      Waste Connections may incur additional charges related to capitalized
      expenditures, which would decrease its earnings; (18) the outcome of
      audits by the Internal Revenue Service may adversely affect Waste
      Connections; (19) each business that Waste Connections acquires or has
      acquired may have liabilities that Waste Connections fails or is unable to
      discover, including environmental liabilities; (20) liabilities for
      environmental damage may adversely affect Waste Connections' business and
      earnings; and (21) the adoption of new accounting standards or
      interpretations could adversely impact Waste Connections' financial
      results. These risks and uncertainties, as well as others, are discussed
      in greater detail in Waste Connections' filings with the Securities and
      Exchange Commission, including its most recent Annual Report on Form 10-K.
      There may be additional risks of which Waste Connections is not presently
      aware or that it currently believes are immaterial which could have an
      adverse impact on its business. Waste Connections makes no commitment to
      revise or update any forward-looking statements in order to reflect events
      or circumstances that may change.
