Scotland will face Sevens World Series champions New Zealand in the quarter-finals having finished second in Pool C of the Glasgow leg at Scotstoun.
Against a backdrop of uncertainty over the future of Scottish professional sevens, the Scots narrowly defeated Portugal and Wales and lost to Fiji.
England drew with Australia on their way to finishing second in Pool A.
Simon Amor's side tackle Canada at 12:42 on Sunday, before the Scots and Kiwis meet at 13:04.
Elsewhere, series leaders South Africa were runners-up in Pool B, losing 24-19 to New Zealand in the tie of the day, but finished ahead of the ever-popular Kenya and Samoa.
Colin Gregor, equalling Scotland's sevens caps record of 57 tournaments, showed fine awareness to dummy and send captain Scott Riddell under the posts for the Scots' first try of the afternoon against the Portuguese, adding the conversion.
The giant dreadlocked figure of Aderito Esteves raced away to level, before Jose Lima brilliantly wrong-footed Russell Weir to send David Mateus in at the corner, Pedro Leal converting both tries.
James Johnstone scored for the hosts on the half-time hooter, and Gregor converted a late Mark Robertson touchdown - Riddell rescued the 19-14 victory with the last play, intercepting an Esteves offload and scrambling over the touchline metres from his own line.
With around three hours between each of their ties, Scotland again fell behind to an embattled but streetwise Welsh team, Dan Fish converting his own try to negate an early Johnstone score.
A seemingly endless, energy-sapping phase that left players on both sides strewn exhausted across the turf finished with a crucial James Fleming try under the posts, handing the Scots a 12-7 win.
Their lack of precision and potency was exploited by a ruthless Fijian outfit, well-drilled under head coach Ben Ryan, in the final match of the day as they seldom threatened to upset the odds, losing 45-5.
Samisoni Virivi, a member of the Montpellier squad that lost to Glasgow Warriors at this venue in January, crossed for the islanders early on, with Amenoni Nasilasila, Josaia Rasuqe and Semi Kunatani grabbing a brace each.
Fleming scored a consolation for the hosts.
"Fiji are a world class outfit and when they control the ball at the restarts they give themselves a flow of possession and they have runners and threats across the field to damage any team's defence," said Scotland head coach, Calum MacRae.
"Day two, it's very important the boys have a steely focus on the job in hand. I don't see this tournament as any different to any others; we've got New Zealand first, we'll approach it in exactly the same way as we've done all year.
"The results have spoken for themselves this year with the consistency we've shown in getting through to Cup competitions."
