Here's a different organization of the same GHG source data for 2004, the most recent publicly available in Canada.
Transportation - 24% (rail and marine are minor components)
Other industry - 20% (includes petroleum refining at 4%)
Electricity generation - 17% (3/4 from coal-fired)
Fossil fuel production - 16% (includes pipelines)
Commercial and residential sectors - 11%
Agriculture and forestry - 8% (excludes off-road transport)
Waste management - 4% (mostly methane from landfills)
The largest single component of "other industry" is manufacturing.
I'd be surprised if home heating was such a small proportion (gas, and wood).
Home and commercial A/C would be buried in the 'electricity' sector. Given how little of Canadian electricity is produced from coal, it's striking what a large chunk of GHGs it produces.
There's a bit of a myth about the magnitude of heating emissions in Canada. GHG emissions from the residential sector in 2004 were 43 MT CO2eq (5.7% of Canada's total), primarily related to space and water heating. According to EC, this figure does not include biomass combustion, however, so it represents primarily consumption of distillate and NG. The inventory lumps the use of wood for residential heating together with emissions from forest fires. In any case, I imagine wood combustion is a small fraction of residential heating.
I agree that home and commercial AC is buried in electricity production, as is the growing use of heat pumps, where the electricity comes from non-renewables.
