Generally what would I need to budget to upgrade a 100 amp panel to a 200 amp?
It depends from many things:
1. Is the service wire size big enough for 200A?
2. Service wire is under ground or over head?
3. Wire size between a Meter Base and Electrical Panel is big enough for 200A?
4. City inspection and utility company service cost.
If we have overhead service wire, usually in case like that, wire is big enough for 200A.
If Under ground service wire, in that case wire size may be to small for 200A. To replace that wire between your Meter and Transformer will cost a lot of money.
Because the budget to upgrade 100A panel to a 200A will be from $3,500.00 and high.
My typical bill out rate for a 200 amp overhead service upgrade here in Peterborough is $2300-2700 using jumbo meter bases and using 60cct panels.

Come May / 2016 everything get more complicated.
With the release of the new Ontario Electric Code.
To replace a 100 Amp breaker panel with a 200 Amp, questions need to be answered and measurements made. An installation estimate without a site visit can be unnecessarily high or come from a non professional. Assuming you are a home owner, a panel rated for 200 Amp can be purchased for under $200 off the shelf. This answer is coming from Edmonton Alberta and for this province I would recommend that you budget for anywhere from $1,500 to $3,000 for a very broad ball park. I recommend site visits and estimates from 3 electrical contractors. The wire coming from the pole to your home must be replaced with a larger size (which is no charge for the wire installation if it is overhead) and installed by the supply authority (power company). All of the wiring (and likely conduit) from where it attaches to the home to the new upsized breaker panel must be replaced. The meter socket must be replaced. For some obsolete existing panels, all of the breakers may need to be replaced. The Canadian Electrical Code changes every few years and the entire installation, with the exception of the existing wiring throughout the home must be compliant with the current code to pass the inspection. The new installation may require a mast to be erected to satisfy the current code. It may be advisable to locate the new panel in another location like the basement which will require rerouting of the existing circuit wiring. Is the existing installation underground? Whatever the cost, a Master Electrician Certificate is required to pull a permit for an upgrade and the supply authority will not connect the new service without it, as well as a passed inspection. Ask to see a copy of the liability insurance cert. and WCB clearance letter. Get it in writing with a guarantee and in the Province of Alberta ask to see their provincial prepaid contractors license before giving a down payment. That license comes with a bond and complete background check on the business owner.
