      Mr

      answered

      affirmative
      and
      
      
      pronounced
      judgment
      accordingly.
      The
      only
      issue
      in
      the
      present
      appeal
      
      
      is
      whether
      he
      was
      right
      in
      so
      doing.
      
      
      
      
    
      As
      the
      wording
      of
      section
      83A
      is
      complicated
      and
      confusing
      to
      anyone
      
      
      not
      familiar
      with
      it
      I
      shall
      not
      reproduce
      the
      section
      but
      shall
      endeavour
      
      
      to
      summarize
      the
      portions
      that
      appear
      to
      me
      to
      bear
      on
      the
      
      
      problem
      raised
      in
      the
      appeal.

      as
      enacted
      in

      provided
      that
      a
      corporation
      whose

      might
      deduct,
      in
      computing
      its
      income
      under
      Part
      I
      of
      
      
      the

      expenses
      
      
      incurred
      by
      it
      during
      the
      calendar
      years
      1949
      to

      year

      years.
      An
      amendment

      for
      the
      cancellation
      of

      transaction
      in
      question.
      
      
      
      
    
      Thereafter,
      in
      March
      1963,
      the
      Sharpies
      Oil
      Corporation
      went
      into
      
      
      liquidation

      shareholders
      who,
      in

      sold

      1964
      the

      Limited

      subsequently
      the

      recommenced

      carried

      business
      the

      1968
      the
      appellant
      claimed
      deductions
      in
      respect
      of
      the
      $2,000,000
      
      
      of
      drilling

      exploration
      expenses

      it
      prior
      to
      November
      
      
      10,
      1960,
      but
      as
      previously
      mentioned
      these
      deductions
      were
      disallowed
      
      
      by
      the
      Minister.
      An
      appeal
      to
      the
      Tax
      Appeal
      Board
      from
      this
      
      
      disallowance
      was
      successful
      but
      as
      already
      mentioned
      that
      judgment
      
      
      was
      reversed
      by
      the
      Trial
      Division
      of
      this
      Court
      and
      the
      reassessments
      
      
      based
      on
      such
      disallowance
      were
      restored.
      
      
      
      
    
      The
      submissions
      put
      forward
      in
      this
      Court
      on
      behalf
      of
      the
      appellant
      
      
      fell
      under
      two
      heads.
      It
      was
      said
      first
      that
      the
      amendment
      of
      1962,
      
      
      which
      broadened
      the
      scope
      of
      subsection
      (8a)
      so
      as
      to
      embrace
      
      
      transactions
      of
      the
      kind
      by
      which
      the
      property
      of
      the
      appellant
      was
      
      
      acquired
      by
      the
      Sharpies
      Oil
      Corporation,
      should
      not
      be
      construed
      
      
      retrospectively
      so
      as
      to
      deprive
      the
      appellant
      of
      a
      right
      which
      had
      
      
      accrued
      as
      a
      result
      of
      the
      incurring
      of
      the
      expenditures
      or
      as
      retrospectively
      
      
      referring
      to
      the
      completed
      acquisition
      transaction
      and
      giving
      
      
      to
      it
      tax
      consequences
      which
      it
      did
      not
      have
      when
      made.
      
      
      
      
    
      In
      my
      opinion
      the
      effect
      of
      the
      1962
      amendment
      in
      question
      was
      
      
      not
      retrospective
      in
      enacting
      that
      in
      future
      taxation
      years*
      
      certain
      
      
      new
      taxation
      rules
      should
      apply,
      which
      referred
      to
      and
      were
      defined
      
      
      by
      the
      circumstances
      and
      effect
      of
      past
      transactions,
      that
      is
      to
      say,
      
      
      as
      applied
      to
      this
      case,
      the
      transaction
      by
      which
      the
      appellant’s
      property
      
      
      was
      acquired
      by
      the
      Sharpies
      Oil
      Corporation
      in
      1960
      —
      a
      transaction
      
      
      which
      in
      that
      taxation
      year
      involved
      no
      tax
      consequence
      at
      all.

      On
      the
      other
      hand
      I
      am
      not
      persuaded
      that
      the
      1962
      amendment
      
      
      is
      not
      retrospective
      in
      denying
      the
      appellant
      the
      right,
      given
      in
      1955
      
      
      and
      made
      applicable
      to
      the
      1955
      and
      subsequent
      taxation
      years,
      to
      
      
      deduct
      in
      subsequent
      taxation
      years
      expenditures
      which
      it
      had
      made
      
      
      by
      the
      end
      of
      1960,
      and
      which
      at
      that
      point
      qualified
      for
      deduction
      
      
      by
      the
      appellant.
      However,
      even
      if
      the
      effect
      of
      the
      1962
      amendment
      is
      
      
      retrospective
      in
      this
      or
      other
      respects,
      the
      language
      of
      subsection
      
      
      83(A)
      (8a)
      which
      results

      paragraphs
      (c),
      (d)
      and
      (da)
      is,
      in
      my
      opinion,
      such
      as
      to
      make
      perfectly
      
      
      clear
      that
      subsection
      (8a)
      as
      so
      amended
      does
      refer
      and

      to
      situations
      of

      here
      in
      question.
      That
      language

      the
      wording
      “has
      at
      any

      1954,
      acquired”
      and
      with
      
      
      this
      may
      be
      coupled
      the
      fact
      that
      the
      wording
      of
      subsection
      (6)
      of
      sec-

      1956
      made
      subsection
      
      
      (8a),
      when
      originally
      enacted,
      retrospectively
      applicable

      The
      fact
      that
      in
      general
      a

      of

      deduct
      is
      contemplated
      by
      subsection
      (8a),
      rather
      than
      an
      
      
      outright
      destruction
      of
      the
      right,
      to
      my
      mind
      also
      tends
      to
      weaken
      the
      
      
      force
      of
      any
      presumption
      against
      retrospective
      operation
      and
      in
      that
      
      
      sense
      to
      support
      the
      view
      that
      subsection
      (8a)
      as
      originally
      enacted
      
      
      was
      intended
      to
      be
      capable
      of
      operating
      retrospectively
      and
      to
      have
      
      
      retrospective
      effect
      in
      some
      situations.
      I
      am
      also
      of
      the
      opinion
      that
      
      
      the
      repeal
      of
      paragraphs
      (c),
      (d)
      and
      (da)
      of
      subsection
      (8a),
      which
      
      
      broadened
      the
      application
      of
      the
      subsection
      and
      caused
      it
      to
      read
      as
      
      
      including
      transactions
      of
      the
      kind
      here
      in
      question
      by
      which
      a
      corporation
      
      
      “has
      at
      any
      time
      after
      1954,
      acquired’’,
      sufficiently
      shows
      the
      intention
      
      
      that
      the
      subsection
      as
      so
      broadened
      should
      also
      be
      read
      retrospectively,
      
      
      the
      effect
      which
      such
      a
      reading
      would
      otherwise
      have
      with
      
      
      respect
      to
      the
      tax
      consequences
      of
      the
      transaction
      in
      prior
      years
      being
      
      
      modified
      by
      subsection
      (15)
      of
      the
      amending
      section
      which
      made
      subsection
      
      
      (8a),
      as
      amended
      by
      the
      repeal
      of
      paragraphs
      (c),
      (d)
      and
      (da),
      
      
      applicable
      only
      to
      the
      1962
      and
      subsequent
      taxation
      years.
      
      
      
      
    
      The
      appellant
      also
      relied
      on
      paragraphs
      (b)
      and
      (c)
      of
      section
      35
      of
      
      
      the
      
        Interpretation
       
        Act,
      
      RSC
      1970,
      c
      I-23,*
      
      but
      in
      my
      opinion
      it
      cannot
      
      
      be
      said
      that
      the
      repeal
      of
      paragraphs
      (c),
      (d)
      and
      (da)
      affected
      
      
      their
      previous
      operation
      or
      anything
      done
      or
      suffered
      by
      the
      appellant
      
      
      thereunder
      since
      paragraphs
      (c),
      (d)
      and
      (da)
      never
      had
      any
      operation
      
      
      upon
      or
      application
      to
      anything
      done
      or
      suffered
      by
      the
      appellant.
      Nor
      
      
      can
      any
      right
      acquired
      under
      them
      be
      said
      to
      have
      been
      affected
      by
      
      
      their
      repeal,
      since
      no
      right
      was
      ever
      acquired
      by
      the
      appellant
      under
      
      
      any
      of
      them.
      
      
      
      
    
      Under
      the
      other
      head,
      as
      I
      understood
      the
      argument,
      it
      was
      submitted,
      
      
      that
      to
      treat
      the
      1962
      amendment
      as
      making
      subsection
      (8a)
      
      
      refer
      to
      the
      transaction
      in
      question
      from
      the
      time
      of
      the
      amendment
      
      
      leads
      to
      the
      absurd
      result
      that
      in
      computing
      its
      income
      for
      the
      taxation
      
      
      year
      1961
      the
      appellant
      would
      have
      been
      entitled
      to
      a
      deduction
      under
      
      
      section
      83A,
      if
      it
      had
      had
      any
      income,
      and
      that
      as
      a
      result
      of
      the
      
      
      amendment
      the
      Sharpies
      Oil
      Company
      would
      also
      have
      become
      entitled
      
      
      to
      a
      deduction
      in
      computing
      its
      income
      for
      the
      1962
      taxation
      
      
      year
      in
      respect
      of
      the
      same
      drilling
      and
      exploration
      expenses.
      
      
      
      
    
      It
      was
      pointed
      out
      by
      Martland,
      J
      in
      
        Hargal
       
        Oils
       
        Ltd
      
      v
      
        MNR,
      
      [1965]
      
      
      SCR
      291;
      [1965]
      CTC
      50;
      65
      DTC
      5029,
      that
      the
      wording
      of
      subsection
      
      
      
      
    
      (8a)
      is
      complicated
      and
      that
      its
      meaning
      is
      far
      from
      clear
      and
      for
      this
      
      
      reason,
      if
      for
      no
      other,
      it
      appears
      to
      me
      that
      the
      Court
      should
      confine
      
      
      its
      attention
      to
      the
      problem
      before
      it
      and
      not
      attempt
      the
      task
      of
      resolving
      
      
      or
      reconciling
      the
      results
      of
      hypothetical
      situations
      that
      may
      
      
      conceivably
      arise.
      Nor
      do
      I
      think
      such
      an
      approach
      will
      lead
      to
      a
      
      
      solution
      of
      the
      present
      problem.
      Rather,
      in
      my
      opinion,
      the
      problem
      
      
      must
      be
      resolved
      by
      a
      straightforward
      application
      of
      the
      wording
      of
      
      
      the
      subsection
      to
      the
      facts
      as
      they
      have
      been
      agreed.
      If
      by
      such
      an
      
      
      approach
      the
      application
      of
      the
      subsection
      with
      respect
      to
      the
      appellant
      
      
      is
      clear,
      that
      as
      I
      see
      it
      is
      all
      that
      requires
      to
      be
      decided
      in
      the
      
      
      present
      appeal.
      
      
      
      
    
      Approaching
      the
      matter
      in
      this
      way,
      whether
      or
      not
      the
      result
      may
      
      
      be
      to
      give
      subsections
      (8a),
      as
      so
      amended,
      some
      retrospective
      effect
      
      
      on
      rights
      which
      the
      appellant
      formerly
      had,
      and
      regardless
      of
      what
      
      
      rights
      if
      any,
      may,
      as
      a
      result
      of
      the
      amendment,
      have
      been
      conferred
      
      
      on
      the
      
        successor
      
      company
      in
      computing
      its
      income
      for
      taxation
      years
      
      
      prior
      to
      1962,
      which
      it
      is
      not
      necessary
      to
      determine,
      it
      appears
      to
      me
      
      
      to
      be
      plain
      and
      clear
      from
      the
      language
      of
      the
      subsection
      that
      upon
      
      
      the
      coming
      into
      force
      of
      Chapter
      8
      of
      the
      Statutes
      of
      Canada,
      1962-63,
      
      
      which
      repealed
      paragraphs
      (c),
      (d)
      and
      (da)
      of
      subsection
      (8a)
      and
      
      
      which
      repeal
      was
      made
      applicable
      to
      the
      1962
      and
      subsequent
      taxation
      
      
      years,
      the
      appellant
      became
      a
      
        predecessor
      
      corporation
      and
      was
      
      
      no
      longer
      to
      have
      and
      no
      longer
      did
      have
      any
      right
      arising
      from
      drilling
      
      
      and
      exploration
      expenditures
      theretofore
      made
      by
      it
      to
      deductions
      
      
      under
      section
      83A
      for
      the
      purpose
      of
      computing
      its
      income
      for
      the
      
      
      1962
      or
      any
      subsequent
      taxation
      year.
      That
      conclusion
      alone,
      as
      I
      see
      
      
      it,
      is
      sufficient
      to
      dispose
      of
      the
      appeal
      and
      in
      my
      opinion
      it
      should
      
      
      be
      dismissed
      with
      costs.
