        J:—This
      
      is
      one
      of

      together,
      from
      orders
      of
      Grant,
      
      
      DJ
      of
      the
      trial
      division
      whereby
      firstly
      he
      ordered
      that
      the
      time
      within
      which
      
      
      an
      appeal
      may
      be
      instituted
      by
      the
      respondent
      from
      a
      decision
      of
      the
      Tax
      
      
      Review
      Board
      be
      extended
      to
      September
      10,
      1978
      and
      whereby
      secondly
      he
      
      
      dismissed
      the
      appellant’s
      motion
      to
      strike
      out
      the
      respondent’s
      statement
      
      
      of
      claim.
      
      
      
      
    
      Briefly
      put
      the
      relevant
      facts
      follow.
      The
      appellant
      appealed
      to
      the
      Tax
      
      
      Review
      Board
      from
      an
      assessment
      to
      income
      tax
      for
      his
      1971
      taxation
      year,
      
      
      which
      appeal
      was
      allowed
      by
      a
      judgment
      mailed
      to
      the
      parties
      on
      April
      24,
      
      
      1978.
      The
      respondent
      filed
      a
      statement
      of
      claim
      in
      the
      trial
      division
      on
      
      
      August
      23,
      1978.
      It
      is
      common
      ground
      that
      the
      statement
      of
      claim
      had
      been
      
      
      filed
      on
      the
      121st
      day
      from
      the
      date
      of
      mailing
      of
      the
      Board’s
      judgment.
      On
      
      
      september
      13,
      1978
      the
      respondent
      moved
      for
      an
      Order
      under
      Court
      No
      
      
      T-3790-78
      extending
      the
      time
      within
      which
      the
      appeal
      might
      be
      instituted.
      
      
      The
      appellant
      then
      moved
      under
      Court
      No
      T-3790-78,
      for
      an
      order
      striking
      
      
      out
      the
      statement
      of
      claim
      on
      the
      ground
      that
      it
      had
      not
      been
      filed
      within
      
      
      the
      time
      limited
      by
      section
      173*
      
      of
      the
      
        Income
       
        Tax
       
        Act
      
      for
      bringing
      the
      appeal.
      
      
      Grant,
      DJ
      granted
      the
      respondent’s
      motion
      and
      dismissed
      the
      ap-
      
      
      pellant’s
      motion,
      both
      without
      reasons.
      It
      is
      from
      these
      orders
      that
      these
      
      
      two
      appeals
      are
      brought.
      
      
      
      
    
      The
      respondent
      seeks
      to
      uphold
      the
      orders
      on
      the
      basis
      that:
      
      
      
      
    
      1.
      The
      statement
      of
      claim
      was
      filed
      within
      the
      time
      limit
      on
      the
      footing
      
      
      that
      under
      paragraph
      3(1)(b)
      of
      the
      Federal
      Court
      Rules
      the
      time
      for
      filing
      
      
      does
      not
      run
      during
      Long
      Vacation;
      
      
      
      
    
      2.
      in
      any
      event,
      the
      time
      for
      filing
      the
      statement
      of
      claim
      may
      be
      extended
      
      
      under
      Rule
      3(1
      )(c)
      of
      the
      Rules
      of
      this
      Court;
      and
      
      
      
      
    
      3.
      in
      the
      further
      alternative,
      the
      court
      had
      the
      power
      to
      extend
      the
      time
      
      
      for
      filing
      the
      statement
      of
      claim
      by
      virtue
      of
      section
      167
      of
      the
      
        Income
       
        Tax
      
        Act.
      
      The
      appellant,
      of
      course,
      challenges
      the
      respondent’s
      view
      on
      the
      applicability
      
      
      of
      the
      court’s
      rules
      before
      the
      institution
      of
      an
      appeal
      particularly
      
      
      because
      of
      the
      existence
      of
      the
      statutory
      limitation
      period
      under
      section
      
      
      172
      of
      the
      Act
      and
      further
      because
      of
      the
      fact
      that,
      while
      section
      167
      provides
      
      
      a
      means
      whereby
      a
      taxpayer
      may
      apply
      to
      the
      trial
      division
      for
      an
      
      
      order
      extending
      the
      time
      within
      which
      such
      appeal
      may
      be
      instituted,
      no
      
      
      such
      right
      to
      apply
      for
      an
      extension
      is
      given
      to
      the
      respondent
      by
      that
      or
      any
      
      
      other
      section
      of
      the
      Act.
      
      
      
      
    
      The
      rules
      of
      the
      court
      and
      the
      section
      of
      the
      Act
      in
      issue
      read
      as

        circumstances
        mentioned
        in
        subsection
        (1)
        or
        (4),
        as
        the
        case

        be,
        an
        objection
        or
        appeal
        would
        have
        been

        within
        the
        
        
        time
        otherwise
        limited
        by
        this

        (ii)
        the
        application
        was
        brought
        as
        soon
        as
        circumstances
        permitted
        it
        to

        and
        
        
        
        
      
        (iii)
        there
        are
        reasonable
        grounds
        for
        objecting
        to
        or

        the
        
        
        assessment.
        
        
        
        
      
      We
      are
      all
      of
      the
      opinion
      that
      the
      contentions
      of
      appellant’s
      counsel
      are
      
      
      correct
      and
      that
      the
      learned
      motions
      judge
      thus
      erred
      in
      granting
      that
      extension
      
      
      of
      time
      to
      file
      the
      statement
      of
      claim
      and
      consequently,
      in
      refusing
      
      
      to
      strike
      it
      out.
      
      
      
      
    
      It
      will
      be
      noted
      that
      the
      opening
      words
      of
      Rule
      3(1)
      are
      “Unlesss
      the
      contrary
      
      
      otherwise
      appears
      the
      computation
      of
      time
      
        under
       
        these
       
        rules
       
        ..(emphasis
      
      
      
      added).
      The
      computation
      of
      time
      for
      instituting
      an
      appeal
      under
      the
      
      
      
        Income
       
        Tax
       
        Act
      
      is
      made
      pursuant
      to
      that
      Act
      and
      is
      not
      made
      
        under
       
        the
      
        rules.
      
      It
      is
      clear,
      therefore,
      that
      clause
      (b)
      of
      Rule
      3(1)
      relating
      to
      the
      exclusion
      
      
      of
      Long
      and
      Christmas
      Vacations
      in
      the
      computation
      of
      times
      can
      
      
      have
      no
      applicability
      to
      the
      computation
      of
      time
      under
      the
      
        Income
       
        Tax
       
        Act
      
      
      
      for
      the
      institution
      of
      an
      appeal.
      
      
      
      
    
      By
      the
      same
      reasoning,
      Rule
      3(1)(c)
      permitting
      enlargement
      or
      abridgment
      
      
      of
      the
      time
      
        “appointed
       
        by
       
        these
       
        Rules"
      
      can
      have
      no
      application.
      Both
      
      
      rules
      apply
      only
      after
      an
      appeal
      or
      action
      has
      been
      instituted.
      The
      time
      appointed
      
      
      in
      this
      case
      was
      under
      the
      Act
      not
      under
      the
      Rules.
      
      
      
      
    
      Turning
      now
      to
      section
      167
      of
      the
      Act
      it
      is,
      in
      our
      view,
      abundantly
      clear
      
      
      that
      subsection
      4
      applies
      only
      to
      a
      taxpayer
      who
      seeks
      an
      extension
      of
      time
      
      
      for
      the
      institution
      of
      an
      appeal.
      We
      reach
      this
      conclusion
      from
      the
      following
      
      
      aids
      in
      the
      construction
      of
      the
      section:
      
      
      
      
    
      (1)
      Subsection
      167(4)
      provides
      for
      service
      of
      the
      notice
      of
      application
      for
      
      
      an
      extension
      of
      time
      on
      the
      Deputy
      Attorney
      General
      of
      Canada
      within
      14
      
      
      days
      before
      the
      return
      date
      of
      the
      motion.
      This
      mandatory
      provision
      is
      
      
      patently
      inappropriate
      in
      the
      case
      of
      an
      appeal
      by
      Her
      Majesty,
      who
      is
      
      
      represented
      in
      court
      by
      the
      Deputy
      Attorney
      General
      and
      thus
      in
      our
      view
      
      
      indicates
      that
      the
      section
      applies
      only
      to
      an
      appeal
      by
      a
      taxpayer.
      
      
      
      
    
      (2)
      Subsection
      (5)(a)
      and
      (5)(b)
      of
      section
      167
      refer
      to
      “objecting
      to
      or
      appealing
      
      
      
        from
       
        the
       
        assessment
       
        .
       
        .
      
      (emphasis
      added).
      Only
      the
      taxpayer
      
      
      objects
      to
      or
      appeals
      from
      an
      assessment—not
      the
      respondent.
      
      
      
      
    
      (3)
      Subparagraph
      (5)(c)(iii)
      of
      section
      167
      requires
      that
      there
      be
      reasonable
      
      
      grounds
      “for
      objecting
      to
      or
      appealing
      from
      the
      assessment’’.
      That
      requirement
      
      
      is
      appropriate
      only
      to
      a
      taxpayer’s
      appeal
      even
      where
      the
      appeal
      
      
      is
      from
      a
      decision
      of
      the
      Tax
      Review
      Board
      since
      such
      an
      appeal
      is
      a
      
      
      trial
      
        de
       
        novo
      
      and
      is,
      therefore,
      an
      appeal
      from
      the
      assessment,
      in
      
      
      essence.
      
      
      
      
    
      From
      all
      the
      above
      it
      is
      obvious
      that
      Parliament,
      having
      given
      a
      lengthy
      
      
      delay
      of
      120
      days
      to
      institute
      an
      appeal,
      intended
      to
      extend
      the
      privilege
      of
      
      
      seeking
      an
      extension
      of
      such
      delay
      only
      to
      a
      taxpayer
      and
      not
      the
      the
      
      
      respondent,
      possibly
      to
      achieve
      some
      degree
      of
      finality
      in
      income
      tax
      proceedings
      
      
      for
      the
      sometimes
      beleagured
      taxpayer.
      It
      is
      trite
      to
      say
      that
      we
      
      
      cannot
      change
      the
      legislation.
      Accordingly,
      the
      appeal
      will
      be
      allowed,
      the
      
      
      order
      of
      the
      trial
      division
      set
      aside
      and
      the
      respondent’s
      application
      for
      extension
      
      
      of
      time
      will
      be
      dismissed
      with
      costs
      here
      and
      below.
